How to Actually Sit Together on a Flight (Even If You Booked Through a Third Party)

Few things sour the start of a holiday like discovering at check-in that your family or travel group has been split across the cabin. It happens far more often than it should, and it’s rarely because the airline set out to separate you — it’s usually a mix of fare type, timing and how the booking was made in the first place.

Why Seating Gets Split Up in the First Place

Airlines release seat maps in stages, and how much control you have over where you sit depends heavily on your fare. Basic or “light” fares booked through comparison sites often don’t include free seat selection at all — you’re assigned a seat automatically at check-in from whatever’s left. If you check in late, or if the flight is full, “whatever’s left” frequently means scattered singles rather than seats together.

Why This Happens More Often With OTA Bookings

This isn’t unique to any one booking channel, but it does come up disproportionately with OTA and comparison-site bookings, for a simple reason: the cheapest fare shown in a search is often the one with the fewest seating perks attached. The OTA’s job is to find you the lowest headline price, not to flag that the fare excludes advance seat selection — so it’s easy to book without realising you’ll be assigned seats at random later.

What Actually Determines Whether You Sit Together

• Fare class: higher fare tiers usually include free seat selection; basic fares often don’t
• Aircraft and route: smaller aircraft and popular routes fill up (and lock in seat maps) faster
• Timing: seats together are far easier to secure well before departure than at the last minute
• Group size: parties of 5 or more are harder to seat together than couples or families of three or four
• Whether you paid for seat selection at all, versus leaving it to automatic allocation

What the UK CAA Says About Children and Seating

The UK Civil Aviation Authority expects airlines to make reasonable efforts to seat children under 12 next to an accompanying adult, free of charge, where seats allow. It’s not an absolute guarantee — a fully booked flight with no adjacent seats left simply has no seats to offer — but it’s a real expectation, and worth knowing if you’re ever told there’s nothing that can be done.

How to Give Yourself the Best Chance

• Select seats as early as your fare and the airline allow — don’t wait until nearer the departure date
• Check in the moment the window opens if you weren’t able to pre-select seats
• Check in your whole party together in one session rather than separately
• If seats are already split by the time you look, contact the airline directly rather than the OTA — the airline holds the actual seat map
