Full-service carriers
Assignment usually opens at ticketing. Standard seats are commonly free, with preferred and extra-legroom rows paid. A portion of the cabin is held back for elite members and released at check-in.

Prebook seats: choosing where you sit before departure
Assignment is not the same as upgrading. This page is about getting seats on the record early, keeping a party together, and avoiding the rows that look fine on a seat map and are not.

Timing
When you can assign, by carrier type
The single biggest factor in whether you get the seats you want is how early you ask. The window differs sharply between airline business models.
Low-cost carriers
Almost every seat is sold. Decline to pay and you are assigned automatically at check-in, frequently a middle seat, and a party booked together may still be split.
Codeshare and interline
The operating carrier owns the seat map. A seat chosen on the marketing airline’s site may not transmit. Assign on the operating carrier’s record, and re-check after ticketing.
Charter and leisure
Maps often open later, sometimes only within days of departure, and assignment is usually paid. Ask before assuming you can choose at all.
When seat maps open, and why it varies so much
There is no industry-wide moment at which seats become selectable. On most full-service carriers the map opens the moment the ticket is issued, which is the single best argument for assigning seats immediately rather than the week before you fly. Airlines hold back a portion of the cabin — commonly the forward rows, the exits and a scatter of aisles — for elite members, for passengers who need them, and for release at check-in, which is why a map that looks full at booking can loosen twenty-four hours out.
Low-cost carriers work on a different premise: every seat is a product, and nothing is free. If you decline to pay, the departure control system assigns you at check-in, usually to whatever is left. It is not a punishment, it is the fare model, and it is worth pricing honestly against a full-service fare that includes assignment before you assume the low-cost ticket is cheaper.
Codeshares deserve their own warning. When you book a flight numbered by one airline but operated by another, the seat map belongs to the operator. A selection made on the marketing carrier's website may not transmit, or may transmit and then be dropped when the operating carrier reissues the record. Always confirm the assignment shows on the operating carrier's booking, and confirm again after any change. This is one of the most common reasons a couple discovers at the gate that they are seated eleven rows apart.
Free versus paid: what you are actually deciding
On a full-service carrier the decision is rarely "seat or no seat" — it is "this seat now, or whatever is left later". Standard seats are usually free at some point in the process. The paid products buy you certainty and location: a specific aisle, a specific row, an adjacent pair.
Answer three questions and the decision makes itself. Are you travelling with anyone whose seat must be next to yours? If yes, assign now, whatever it costs — the price of two adjacent seats is always less than the cost of the argument. Does your status or fare already include assignment? Add your loyalty number to the record and look again before paying for anything. Is the flight long enough that location matters to how you arrive? On a nine-hour overnight sector, yes; on a ninety-minute hop, usually not.
If none of those apply, waiting is a perfectly rational bet. Free seats are frequently released at check-in as the airline finalises the cabin, and a solo traveller with no strong preference loses very little by taking what appears.
Basic economy and assignment at check-in
Most basic economy fares exclude advance seat selection by design. You are assigned automatically when check-in opens, and passengers on the same booking are not guaranteed to be seated together — including adults travelling with children, though family-seating policies increasingly carve out young children.
The honest way to price this is to compare like with like. Take the basic economy fare and add the cost of buying seat assignments separately, if the carrier even permits it, then compare against standard economy. On many routes the gap between the two fares is smaller than the seat charges, at which point basic economy is not the cheaper ticket. Our advisors run that comparison out loud rather than quoting the lowest headline number — the wider logic is on how flight pricing works.
Aircraft quirks a seat map will not tell you
A seat map shows a grid. It does not show what the seat is like, and the differences are consistent enough to plan around.
- Seats that do not recline. The last row of a cabin, backed by a wall or galley, and the row immediately in front of an exit. Both are frequently sold at ordinary prices without a warning on the map.
- Misaligned or missing windows. On several common narrowbody and widebody types, certain window seats sit between two windows or have none at all, because the cabin's seat pitch does not match the fuselage's window spacing. If you sleep against the window, this matters more than the row number.
- Bassinet positions. Fitted at bulkheads on long-haul aircraft. Excellent if you are travelling with an infant, less so if you were buying the bulkhead for quiet.
- Galley and lavatory adjacency. Light, noise and queueing traffic for the whole flight. The seats immediately forward and aft of a galley are the ones to avoid on overnight sectors.
- Fixed armrests and in-armrest trays. Standard in exit rows and bulkheads. They narrow the usable seat, which offsets some of the legroom you paid for.
- Curvature and misaligned rows. Toward the front and rear of the fuselage, the cabin narrows; window seats there can lose foot space to the wall.
None of this appears on a booking page. It comes from knowing the configuration flying your route on your date, which changes when the airline swaps types seasonally. Ask before you pay — the detail on what each seat product is worth is in upgrade seats.
Sitting together: groups, families and the practical method
For a party of two to nine, the reliable method has three steps. Book everyone on one reservation so the system treats the party as a unit. Assign seats immediately after ticketing rather than closer to departure. Re-check the assignments after every schedule change, because reallocation does not preserve who is travelling with whom.
For larger parties, ask us to block a section rather than selecting individual seats. Blocking a contiguous group of rows is ordinary agency work and it is far more effective than nine people clicking a map at different times. Group bookings ticketed under a group contract have their own seating process and their own deadlines, covered in flight reservations.
For families, US Department of Transportation expectations push carriers toward seating young children adjacent to an accompanying adult without an additional fee, and several US airlines publish commitments to that effect where adjacent seats are available at booking. The operational reality is unchanged: seats assigned early on the record are seats you have; seats promised at the gate are seats you are hoping for. Tell us the ages of the children at booking so the request is coded rather than improvised.
Equipment swaps: what happens to your careful planning
Airlines substitute aircraft for maintenance, crew or demand reasons, sometimes weeks ahead and sometimes on the day. When the type changes, the seat map changes and the departure control system reallocates everyone. Rows disappear, exit locations move, and a party carefully seated together is scattered.
Two habits protect you. Re-check assignments whenever you receive a schedule change or an aircraft change notice, and check once more when check-in opens. Where a paid seat product is no longer provided — you bought an exit row and the substitute aircraft has put you in a standard middle — ask for the charge back; carriers generally refund or re-accommodate, but rarely without being asked. If your booking is with us, call and we will make the claim and re-seat the party, applying the refund policy to any charge of ours and pressing the carrier for theirs.
If a swap is part of a wider disruption, seats are the second problem, not the first: see flight changes for reaccommodation, and check that anything waiting at the other end still lines up — a rental counter with fixed hours, and the late-arrival hold on wherever you are staying.
Seat map cheat sheet
Rows to think twice about
| Position | Why it looks good | What is often wrong with it |
|---|---|---|
| Row in front of an exit | Near the extra-legroom rows | Frequently does not recline at all |
| Last row of a cabin | Often free, sometimes empty | Limited recline, galley and lavatory traffic |
| Bulkhead | Nobody reclines into you | Bassinet positions, narrower seat, no stowage at take-off |
| Exit row | Most legroom in economy | Fixed armrests, eligibility rules, cold near the door |
| Rear window seats | Window and a wall to lean on | Fuselage curvature reduces foot and shoulder space |
| Mid-cabin window on some types | Ordinary window seat | Window may be misaligned or absent entirely |
Answers
Seat assignment questions
Answered against the rules that actually govern the booking — the carrier's filed fare, the rental agreement, the regulation — rather than from general advice.
When do seat maps open?
It varies by carrier type. Full-service carriers usually open assignment as soon as the ticket is issued, though they hold back some rows for elite members and for check-in. Low-cost carriers normally sell every seat from booking and assign nothing free. Charter and some leisure carriers open assignment closer to departure. On codeshares, the seat map that matters is the operating carrier's, not the one whose flight number you booked.
Why can I not choose a seat on my basic economy ticket?
Because the fare excludes it. Most basic economy products assign seats automatically at check-in, or allow you to buy an assignment separately. That is the fare working as designed, not a fault. If sitting together matters — a couple, a family, anyone anxious about flying — price the gap to standard economy before you buy the cheaper fare; it is often smaller than the cost of buying seats separately.
Do I need to pay, or will free seats appear later?
On most full-service carriers, free standard seats are available at some point — often at booking, and almost always at check-in. The question is whether the free seats remaining will be together and where you want them. If you are travelling alone and relaxed about location, waiting is a reasonable bet. If you are two or more, or you need an aisle for a specific reason, assign early.
How do I get a group seated together?
Book the party on one reservation where possible, so the system treats you as a unit, and assign seats immediately after ticketing. For larger groups, ask us to block a section rather than picking seats one by one — that is straightforward for an agent and awkward through a website. Then re-check assignments after any schedule change, because reallocation does not respect who is travelling with whom.
Which seats should I avoid?
Rows immediately in front of an exit and the last row of a cabin frequently do not recline. Seats beside galleys and lavatories carry light and traffic all night. Some window seats on certain aircraft are misaligned with the window or have no window at all, which matters if you sleep against it. Bulkheads carry bassinet positions on long-haul. None of this is on the booking page; it is on the specific aircraft configuration, which we check.
What happens to my seat if the aircraft is swapped?
Assignments are reallocated automatically, and the row you chose may not exist on the replacement aircraft. Groups get split, paid products disappear, and nobody is notified in a way most passengers notice. Check your seats after every schedule change and again at check-in. Where a paid seat is no longer provided, ask for the charge back.
Does an infant get a seat?
An infant under two travelling on an adult's lap does not occupy a seat and is normally ticketed at a percentage of the adult fare on international routes, or a small fee domestically. If you want the infant in a car seat, you must buy a seat for them — and then the car seat has to be approved for aircraft use and, on most carriers, cannot be placed in an exit row or a bulkhead position with an inflatable belt. Tell us at booking so the record is coded correctly.
Can you assign seats for me after I have booked?
Yes. Seat assignment on a booking we hold is ordinary desk work — call with the record locator and we will look at the live map with you. Where the seat itself carries an airline charge, that is the carrier's price and we pass it through unchanged; any service charge of ours is published in the fee schedule.
