Good flight. Connector flight was delayed so made a short turnaround in Atlanta which was stressful. Otherwise, great crew, Staff in ATL was very informative about the delay and ensured people their connections were fine. Notified the ones that were not. Great communication.

Good flight. Connector flight was delayed so made a short turnaround in Atlanta which was stressful. Otherwise, great crew, Staff in ATL was very informative about the delay and ensured people their connections were fine. Notified the ones that were not. Great communication.

The flight went very well, but the flight attendants didn't serve and food or drinks other than 1st class due to rough air but to be honest it wasn't that bumpy and I felt that they could've at least offered water and coffee perhaps. Also serving 1st class only is a bad look. I've been in 1st class many times and I would've felt that if the turbulence was too rough for the main cabin, it would be too rough for 1st class too.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

My seatback screen didn’t work so that sucked because that’s what I was going to do on the plane.

Left a few minutes early. Got in 15 minutes early. Very attentive service on board. Very organized boarding.

The whole experience was excellent. As it most often is with Delta

Cabin was not pressurized properly. Several passengers had respiratory difficulties.

I was happy that I was able to get a last minute flight but unfortunately my seat was a middle seat. Even with Delta Comfort I wasn't comfortable

There’s not much to say about a one hour flight. This is a connection from LA to RNO that I missed the previous night due to a mechanical check delay on my originating flight from JFK to LAX. The short flight itself was fine. Instructions from the pilot and crew were per usual. The coffee was barely lukewarm, which possibly was purposeful so we would down it quickly. Bags were already on carousel upon reaching baggage claim, which was excellent.

Flight was warm for first few hours and quite rough

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.

Great. Has a problem with DOB. Fixed 4 us. Led to a 5 hour earlier flight to London!

One of the best flight experiences I've have had in along time. Would fly with them again.

So, the trip from Dublin to LA did not really happen because the flight took off before we could finish the transfer.

Very nice experience. Flight had good entertainment system and good food options. Customer service was very friendly and nice as well.

Like - the crew were nice Dislike - sitting on the tarmac for long periods after boarding and landing.

I was not admitted to the flight!!! i need a refund for this.

It’s my new favourite airline! Everything was smooth and relaxed!

One of the best flights I've been on in a while. Very genuinely friendly staff. Courteous, kind, respectful. On a past flight (not Aer Lingus) I remember being woken up rudely to put my seat forward. Like a child being berated for something. Oddly jarring experience when someone could just tap you gently on the shoulder and gesture kindly. But I noticed the Aer Lingus staff were incredibly patient with everyone on the plane. It's the holiday season and I noticed a lot more elderly customers on the plane than I typically see flying, and the staff went above and beyond with helping accommodate people. Service throughout the flight was flawless. They came through offering water, and picking up garbage at perfect intervals. Seemed like this flight, everyone was on point. And the flight landed early on top of that

They are rarely on time! Very hard to plan your travels when flights or connections keep getting delayed.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

why would I bother with this airline and pick seats when I am asked to move for a weight imbalance

Flight pulled out on time but sat on runway for 30 mins. It was extremely cold in the aircraft despite wearing a winter coat. Surprisingly they had a vegetarian meal but could have some better snack choices for a 8 hour flight.

We had a male flight attendant who was super attentive and wonderful! Very professional. I have both gluten and dairy intolerance, and was only able to get a gluten free part, and not the dairy free part of the meal. Easy to order ahead of time and I appreciate being able to do that.

Snow delayed boarding several times, which I understand happens. Issue I had was that after we did board, pilot told us we were going to roll out to be de-iced, then on our way. We were de-iced once, taxied to the tarmac and then stopped. Sat for another 30 minutes or so, the another de-icing. Then we rolled out to a parking spot, only to sit for another hour due to a traffic stop in DCA, which I'm confident they knew would happen before we boarded. Pilot gave no updates other than we had to hold, attendants did speak to the crew, but when asked, said the pilot would be updating us. We on the ground in the plane waiting for over 2 hours. They did communicate that bathrooms would be open, but no other news until we left. Would have been better to be up front about status.

Good crew and flight was on time. It’s a small plane with limited overhead luggage space. They said the overhead space was full and I had to check my bag. There was still space when I got on. Waiting for my checked luggage added 30 minutes to my trip. Not the end of the world but also not great.

My seat was assigned last row behind restrooms No legroom’s I’m very Pettit Still was not comfortable Food choice was excellent

Delayed initially because they couldn’t print the flight details. Poor instruction on delay. When I got on the plane the flight attendant argued with me about whether my carry on would fit (it did, although she didn’t acknowledge that). No greeting (other than arguing with me) getting on or off the plane.

Got denied my flight was told on Google that Air Canada was supposed to book me a flight back home because I never was able to go to my destination. They did not help me whatsoever. I had to book a whole new flight for that reason I would write this is zero

The plane was delayed an hour. Heard from other passengers that the Vancouver connection to SFO was never on-time.

My experience was good with United too But only not so good thing was that at Calgary airport I was not given lounge access despite of flying business. Aspire lounge denied it to me, which was unfair I feel

We left over 2 hours late and they didn't even give us a complimentary snack, when getting to the desk I asked if I could be put in a row with only 1 other person or an empt y one I was told the flight was full when the last two rows were empty. All around over it

they were super helpful. Agents at the desk got me on an earlier flight and I was able to get home several hours earlier.

This is a great non-stop YVR-MIA. Very comfortable plane, and no transfer through a city that gets major winter weather!

Terrible…. Reported missing luggage’s with injectable meds that needed refrigeration. Yet, delivery could not be expedited. Luggage’s were delivered 5 days after arrival. The meds were useless as ice pack had melted. So disappointed!!!

Air Canada’s problems are not staff related by and large, no. The problem is tiny jets between the U.S. and Canada - yes, believe it or not they are still “international” (just ask our own Mango Maniac in power in the U.S.). The little aisle is compounded by a design flaw of a “dog leg” starting at seat 12. Woe be unto you if you sit here as passengers and attendants do not have sufficient room to not hit you in the face with backpacks. One thing I will say very positively about Air Canada is you still provide pillows and blankets on transcontinental flights to all, not just the elites. Your tiny improperly designed jets are also a problem flying city to city within Canada also. One can only say you remind us of a “Jet Blue” or “Spirit” experience. Also your luggage space is downright Byzantine! We will endeavor to avoid you and use other U.S. carriers, albeit charging more.

Terrible canceled flight and lost my luggage. Flew me to Halifax. Tgat flight was delayed, had to spend night in airport chair.

Better entertainment & food options more may be adding chicken option or on vegetarian side good quality pasta

I paid for a very expensive Business Class seat to and from Cairo Egypt from Charleston SC. There was partnership from states to London using American Airlines. That leg was amazing. The British Airlines leg was a joke. They used the standard no leg room 3 by 3 seats. A tray was put on the middle seat. The trip was 5 hours, from London to Cairo, thus my BC purchase. There was no screen proving tv/movie options, only a small device plug. The fold down tray and the bag of peanuts were typical of normal short run flying. The one toilet was located in the galley. We all got to know each other well. This was my first and last trip with British Airlines. I now understand why they would NEVER give me a seat chart so that I could make a selection.prior to departure. It honestly would not have made a difference, there were less than 50% of occupied seats. Apparently everyone got the memo but me. I have never felt so cheated as with that trip, got to so another going back to London, yeah. I will be sending a letter to customer service and asking for a refund. I will be photos comparing the two BC legs. OH, one more thing. The FC ticket holders got bulkhead and exit row seats. I know they had to be thrilled

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

The seats were comfortable. So many empty seats allowed for stretching out and sleeping. The onboard entertainment was pretty good. The cabin crew were so kind and kept the passengers well- hydrated, and well fed.

We had American Airlines on our return and it was confusing if we were going with Aa or BA I had 2 different flight numbers and didn’t get our gate until it was boarding. So we were a bit nervous as the which it was

Our Jackson, Mississippi to Dallas Fort Worth flight was delayed on 1/19/26.. This was changed to Jackson to Charlotte in the last minute because of this delay. This started some kind of disconnect between American Airlines and British Airways bookings. We could not go past the passport control in London Heathrow. I had to go to the counter and waited for more than 30 minutes to get a new boarding pass. Problems did not end there. Somehow our entire return flight was canceled by someone. I had to make several phone calls over several days to fix the problem – this was not easy from India. Looks like there was some kind of disconnect between two airlines or some agent did not do it right. I’m anxious to know what went wrong.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.
