Your Step-by-Step Strategy: Getting Seats Together
Follow these steps to drastically improve your odds of sitting together as a family.
Research Airline Family Seating Policies
Start each search with a review of family seating rules for each airline.
Policies differ a lot. Some airlines are better than others; check if advance seat assignments are included in your fare.
Book Early and Avoid Basic Economy
Earlier booking = more seat map options.
Basic economy fares often exclude seat selection or charge for it. Upgrade if family seating matters.
Select Seats At Booking
Pick seats immediately—even if you pay extra.
The seat map can change, but grabbing assignments when booking gives you the best shot.
Reconfirm and Check-In Early
Airlines can shuffle seating close to departure.
Set a calendar reminder to check your seats and check in as soon as possible to avoid involuntary seat changes.
Escalate Issues at the Airport
If separated, calmly ask gate agents for help.
Be polite and persistent. Agents can sometimes help, but know the flight may be full.
