Family Seating: It's Complicated and Costly to Get Wrong

While the Department of Transportation urges airlines to seat kids with families, there is no national law requiring it. Policies, fees, and results vary widely by airline, fare type, and route. Knowing the rules in advance prevents surprise fees or the stress of splitting up at the last minute.

What's Included vs. Not with Family Seating

Usually Included

  • Ability to purchase seats together on standard fares
  • Some protection for kids under 13 on major airlines
  • Gate agent assistance if separated

Not Included

  • Free seat selection on basic/ultra-low fares
  • Guaranteed adjacent seats for adults and teens
  • Seat reassignment on a full flight

Your Step-by-Step Strategy: Getting Seats Together

Follow these steps to drastically improve your odds of sitting together as a family.

01

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.

02

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.

03

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.

04

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.

05

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.
