If continuing from LAX on SkyWest, be prepared for a long walk followed by a bus transfer, and get your necessities before you leave the main terminal areas.

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

Seats were not super comfortable and food was not good at all. If I had a chance I would definitely fly a different airline. Of course they are better than any budget airline, but not by much.

My food prefer was confirmed by email 2x and still the crew claim they had no pre-order. I taken ill while in India so I needed to avoid Indian sauces and spices, so the problem with the preorder was unacceptable. Additionally, is there a new rule to automatically not to disturb passengers? I would like this as an option. Lastly, for breakfast I needed to avoid Indian and I’m allergic to eggs.. therefore the only option was pancakes and guess what was not available!!!

Really hard landing... as in slammed into the runway then hit the brakes really hard ...

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

We had excellent customer service despite the chaos at George Bush airport in Houston!

No seat back entertainment. And app had a hard time getting entertainment loaded.

My flight was canceled a few hours before boarding. I was rebooked on Copa airlines and missed an important meeting .

Poor. Crew allowed children to run around and scream and disturb passanger’s seats.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

On time, only a little turbulence, very competent and caring attendants. Clear information.

The flights are literally always delayed arriving, boarding and taking off so they are always late for the connection. I planned ahead so I was okay but many others aren't. The food was terrible. The staff was very pleasant. I appreciate boarding back to front.

On a four hour delayed flight now on seats back end of the plane instead front-

My issue is with the SkyWest terminal. The flight was not listed on the main airport flight screen list, and I had to do a Google search to locate the terminal and gate. We had to ask several airport employees where to locate the phantom gate. The airport did not provide adequate signage and was confusing. When we arrived, there was one vendor providing services that quickly closed, leaving zero options for food and drink while we waited hours for our delayed flight. The crew that assisted with check-in and boarding was VERY friendly.

Economy seats a bit small but other than that it was all good.

Checked in ok for 3 flights at the airport check-in desk, but apparently I was not checked in to my connecting flights even though I was assured that I was and had seats on all 3 flights. Aer Lingus departure was also delayed for 1.5 hours which gave no time to collect bags to go through customs.

No complimentary drinks or snacks offered on a 2 hour flight was disappointing but everything else went well

All aspects were excellent - it helped that the flight was only 2/3 full and I had no one sitting in my row. The Pre-check (US Passport Control and Customs) in Dublin made everything so easy when we arrived in Chicago.

I love the direct flights. It saves a lot of hassle and allows immigration and customs in Ireland, making arrival much easier.

I would like a refund for the extra cost the seat I paid for. An oversized person sat next to me and I couldn’t fit on my seat and had to move to another seat.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

Got home at 3am after deboarding the plane. No compensation offered by American

The flight was on time and the landing was very smooth. The crew and flight attendants were all very friendly and professional.

Wifi was spotty. Tray table was very dirty when I sat down.

Everything was excellent and I enjoyed myself. Thank for everything

Didn't make it back on American Airlines due to a maintenance issue. The communication and updates were terrible. I ended up returning on Aero Mexico which had a much nicer aircraft with a large entertainment screen with movies and shows AND they had a nice inflight meal. That was a treat after being delayed 26 hours! I think some additional flight miles, or something should be offered for that long of a delay ---it was not pleasant at all---very physical and emotional experience.

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

I cancelled my ticket less than 24 hours deadline but I didn’t get refunded.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

Flight was diverted to bologna due to fog sfter circuling hours in air

there was no food or entertainment on that short 1.5 hour flight unless you mean the cookie and the overhead announcements... Those Q-400's are the workhorse of the rugged coast and mountains for sure.

What a silly survey to send - all AC flights were cancelled due to the strike so of course we did not fly yesterday

It would have been better if it wasn’t cancelled

Flight was canceled due to labor dispute. Their customer service said I might be ok since strike was on sat. and I was flying Friday. The next morning it was canceled. It can ruin a trip and add stress.

I wish to travel with Air Canada for my next trip

When I came in the front door in Montreal airport I didn't know where to go, first time traveling. Signs were not directing me.

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

Great flight ✈️ I requested a vegan meal and don’t think offering frozen fruit cup for breakfast is a good idea people want something warm or neutral like the muffin but it was cold from being in the paper bag with the frozen fruit 🧐 and unfortunately I didn’t have either and I don’t like wasting food so that was a disappointment. Flight was on time departure and arrival flight crew were good.

Flight was in business class on an older Lufthansa 747. Business class seats definitely old style. Flight attendants were a little curt but attentive. Movie choices did not include anything that would be considered new releases.

The map feature on the display at the seat had challenges. The biggest issue was the flight had no WIFI. Most of the smaller planes now have free WIFI. American Airlines on the flight over had WIFI you could purchase. With 8-10 hours on a single flight, the ability to do work via WIFI is essential!!

Overall ok. Best part has always been the sundae dessert.

No WiFi. No food. 250 ml of water only drink option. No entertainment options. Extremely bare bones flight

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

The to flight was excellent but the return flight the seats seemed not cushioning enough.

Overall it was not a pleasant experience, I was given the middle seat even though I asked for a change they didn’t honor

The crew was very nice and pleasant. We were very reluctant to book our flight with British Airlines because we had bad experience with their flight attendants on the previous trips, they were rude and not helpful.

I have always been pleased with their service. Would not change a thing

Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.

As I have said it sucked, the ticket counter to have to find and pay for another airline to get home. Now I understand this happened over the weekend but they should have someone there to talk to us instead of throwing the regular crew under the bus.
