3 hours late departure with no explanation. $160 luggage fee (two passengers) for less than 1 hour in the air!

I sleep on flights. So not a critic of aintertainment. If I can muffle the engine e noise which is difficult sitting at the wing. Generally it was all OK .

Flight was delayed by 45 min. No problems. Everyone took it in stride.

Crew was friendly and helpful; cabin seemed roomy even in economy class.

The flight attendants that assisted me were exceptionally nice, kind and helpful

Something wrong with the plane so had to deplane and waited over 2 hours to finally leave

AC needs to update their fleet. Too many mechanical issues, dated planes and too many delays

The flight was delayed for 4 hours and the airplane was really old cuz not one thing was working.

They charge 5 dollars for plastic headphones for a flight of 1 hour! Seats are awful. Service is terrible.

Nice crew - very small plane and uncomfortable, with no entertainment options…
