You may choose to purchase your little one his/her own seat and use an approved car seat on the plane. Since this is the safest way to travel, we encourage you to do so, if you can. Our seat widths vary depending on the size of the aircraft. Minimum seat widths on the A319 and A320 are 17.4" and on our A321 minimum seat widths are 16.5".
Car seats must be pre-approved with air-travel-approved FAA (Federal Aviation Administration) labels. If they do not have a label, the car seat may be checked-in only. Booster seats may not be used during take-off and landing but may be used during flight.
Car seats cannot be placed in emergency exit rows, in the rows directly in front or behind of emergency exit rows, or in the very first row. We also suggest placing car seats in window seats so they do not impede access to the aisle by other passengers.
