So UA isn't following their on rules on the maximum number of pets in the cabin?
- Two pets per flight are allowed in our premium cabins on select aircraft. Pets are not permitted in our premium cabins on Boeing 747, 757, 767, 777 or 787 aircraft due to limited storage space under the seat.
- Four pets per flight are allowed in United EconomyŽ on all United flights.
- A customer traveling with an in-cabin pet in United Economy on Boeing 757-200 aircraft will need to be seated in a window seat due to limited storage space under aisle and middle seats.
