There is basically only one thing you need to know to be able to plan a flight with twin babies (defined: under 2 years old).
There are only FOUR oxygen masks per row on a plane.
When I say ‘row’ I am not including any aisles. So even though “Row 14” may have 6 seats, for the purposes of this information, “Row 14” has a “left 3” and “right 3” side (“2 rows”).
The flight attendants will only allow 4 people to sit in a row, including lap infants in the total. So if you’re traveling with twins by yourself, you’re fine because one twin will require his/her own seat.
So: you + lap twin + other twin + stranger = 4 people.
But, if you’re traveling with another adult:
You + lap twin 1 + other adult + lap twin 2 + stranger = 5 people.
That’s not allowed.
So decide ahead of time: how do you want to sit?
The main 2 frugal options are either choosing two seats across the aisle from each other or sitting in two rows, one in front of the other. Unless you’re really not fond of the other adult traveling with you. If that’s the case, assign them a seat half a plane away from you 😉
There is another option that I am super fond of if you are traveling as a family of 4, with no other kiddos or adults: If you can afford to, buy all 3 seats in the row and enjoy the extra space. There are still only “4 people,” but you have the middle seat to use for anything: prepping bottles, holding the diaper bag, changing babies into jammies (or changing a diaper during turbulence! Don’t judge!), or a play area for the kids. Technically, one of the children is assigned to that seat, but that doesn’t mean that anyone has to actually sit there.
Enjoy your arm & leg room!
