How to add your dog to a booking

  1. Reserve your pet in advance, because space is limited. Buy the pet add-on on aveloair.com or call Avelo's Customer Solutions Center at (346) 616-9500.
  2. Pets are accepted first come, first served until capacity is reached.
  3. Check your pet in at the airport check-in counter and pay the pet fee before you go to the departure gate.
  4. At security, hold your pet and walk through the screening device while the carrier is x-rayed.
  5. You board with your normal boarding group unless you qualify for preboarding or bought Priority Boarding.

Pet fee

All flights

each way, per carrier

  • Avelo's page calls the charge a "pet fare". The fee is per pet carrier, and one carrier may hold up to two animals.
  • Avelo's Contract of Carriage says pet fees are nonrefundable to the original form of payment unless the flight is cancelled under Section 12(A)(i).
  • Avelo's pages don't say what the fee is for a second animal in the same carrier beyond "per pet carrier". Confirm with Avelo.

Carrier size and weight

Avelo doesn't publish a weight limit for pets in the cabin. What matters is the carrier: your pet has to fit inside it, and it has to fit under the seat in front of you.

17 × 9 × 13 in

≈ 43 × 23 × 33 cm (L × W × H)

  • Soft-sided and hard-sided carriers are both accepted. The carrier must be leakproof and well ventilated, and your pet must be able to stand up and turn around in it with ease.
  • Pets must be at least 8 weeks old.
  • Up to 8 pets are allowed per flight.
  • 1 carrier per passenger, with up to 2 pets of the same species inside.

Where you can sit

Also good to know

  • Avelo's Contract of Carriage says it accepts "small vaccinated" pets. Avelo's pets page says it doesn't require a health certificate or other vet documentation. Confirm with Avelo what proof of vaccination, if any, you need.
  • Pets must stay in the carrier, including head and tail, at the gate, during boarding and deplaning, and for the whole flight. You can't hold your pet on your lap.
  • Avelo can refuse a pet that shows aggressive behavior or other traits it considers incompatible with air travel. It says the pet must be healthy, harmless, inoffensive, odorless and need no attention during the flight.
  • Avelo may require you to buy an extra seat for the pet of a customer with unique seating needs.
  • A customer with a trained service animal who also brings a pet must buy a non-refundable extra seat and put the carrier under the seat in front of that extra seat.

Cargo and checked pets

Avelo doesn't carry pets in the cargo hold, so a dog that doesn't fit in an under-seat carrier can't fly with Avelo.
