Arm rests are too small and too close. No screens, movie selection was very limited and poor. Food is pretty much overpriced cheap convenience store food.

Crew was good, helpful. Flight ran on time.would have liked to take airtransat home to MTL. But the price back from San Jose Costa Rica was MUCH more expensive than the flight from MTL to San Jose c.r.

The on-board crew were professional and friendly and made the trip feel like we were taken care of well. The gate for the flight departure changed three times...not great but not terrible. Considering it was the day of the New Jalisco Cartel mayhem, we can't really complain.

Onward flight was okay. return from Lisbon was poor as we missed our flight due to a long line at the passport control. Air Transat made no effort to accommodate us even though we were at the passport control 40 minutes prior to the departure.

Thank you for making my first experience very enjoyable. You made it all very pleasant

Great flight great seats will absolutely fly with you again

YUL AIRPORT is the worst. 1 Hr to Get out of the plane, 1 Hr To Cross the Border. 1Hr waiting to be pick up curbside. Trafic is ubeliveble.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

Seats were very tight especially for first leg of trip.

The flight and crew were good. Departure and arrival were timely. Check-in was professional and helpful in Malaga on return trip (same on outbound trip from Toronto). The ad before ach program was punishing - specifically for the internet/data service with the content creator that was showed twice in each ad pod. It was so annoying I made an effort to forget the name and would not use the service. Provide an opportunity to fast forward or skip the darn ads once they have been initially viewed.

AA was a very good experience. The employees are wonderful

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Was a normal flight but it was delayed, and there wasn't an explanation.

We had a very pleasant flight with very comfortable seats and nice staff.

Seats in coach aren't padded enough for a 6 hour flight

My trip was delayed for more than 3 hours without any explanation. Also I have a business meeting that I lost.

the handling of my luggage. It was Lost or stolen At my destination.

I rarely vote ‘Excellent’ but this AA flight out of LGA was amazing. On time departure, early arrival, amazing crew, smooth flight, baggage came out quickly. It was the best airport/ flight experience that anyone could ask for/dream of. Highly recommend. I usually fly Delta but American Airlines really stepped up their game.

If we travel with carry on expected to being able to carry the luggage. Could be good if take in consideration the date of reservation to do that

Uncomfortable seats at row 40 A and 40 C, they didn’t recline. Also, my prior seat selection was not honored.
