This is hands down the best airline I've flown with my dog. Check-in was a breeze, La Compagnie has their own security line at the airport, giving me more time to walk Buster, rather than standing in line. Staff is super friendly and accommodating. Highly recommend La Compagnie <3 This is hands down the best airline I've flown with my dog.
