I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

Great list of movies, seat was generally comfortable, but not much shoulder room. The fresh baked cookie mostly made up for the lack of variety with the meals, which were all tomato based.

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

The WiFi has been awful on my last few Delta Air Lines flights.

Did not live up to expectations - lounge benefits of Delta Amex Reerve card not honored for my wife.

Unfortunately I was stuck next to someone who should have purchased 2 seats instead of taking up their space and mine. I couldn’t move the entire 3+ hour flight. Very uncomfortable flight.

Overall, the flight from Atlanta to Orlando was acceptable, albeit delayed and the typical temperature issue on the plane (hot) which has become somewhat expected. However, the staff at gate B22 for connecting flight DL1562 was disappointing. And to clarify, there were two gentlemen behind the counter — one pleasant and the other, Larry. Without question, Larry should not be in hospitality. My wife and I were first in line and when Larry walked in behind the desk, my wife greeted him with “Hiii Larrry”. And while she can be bubbly at times, and I get that it was late, the conversation morphed as Larry asked if she was drunk. At first I assumed he was joking (still not appropriate) but he was not. Clearly he was having a bad day or maybe just hates his job. In all cases, his behavior was unacceptable and offensive. The only saving grace is that he was equally rude and dismissive to all of the surrounding guests as well—although, I’m not sure if that is a good thing or not.

Delay getting into gate in ATL caused delay in bags when getting to BWI, disrupting evening plans with family.

Love delta but the delays and long waits for updates was just too much this time.

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

I love United was disappointed we had a two hour delay, however the Pilot did say safety first.

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

Maybe add a seat trade app for flyers that didn’t get seats together

The crew were very nice. The Chocolate is good and v there’s no entertainment. Thanks

Not the best. Mean. Didn’t give any value to me being a united silver member and lots of attitude.

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Everyone was nice. It was on time and the food was. Airplane food, but not horrible

Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.

Customer service for American Airlines first class is at an all time low.

Terrible. Extremely expensive. Monitor wasn’t working the whole flight 11 hrs and American didn’t offer anything. Change of seats, wifi etc. I’m expecting q compensation from the airline

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

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

Its usually good but this flight was just mediocre. It WAS, however, on time, and got us home early. We had asked for a special meal. The one we got was not what we had requested and the staff said there were no extras so we my family essentially went without food on this 10 hr flight. Not the end of the work. Breakfast was a dry cold bun with some salad leaves and a slice of tomato. That’s it. Skipped it too and ate at home. I expect better from American.

Promised lounge access, gate agent didn't allow us entry.

The flight was very smooth, crew were fantastic but food was lacking.

Flight was good. However, they had everyone board the plane then made us sit there on the tarmac for an hour plus due to maintenance issues. Besides that flight attendant and pilot were amazing.

Flight from Costa Rica to Madrid was excellent. Good food and service. The flight from Madrid to Brussels was very poor . No food , no entertainment, no usb … Total package was quite expensive so you should give same service on the second flight

We travelled with Level, which is a subsidiary of Iberia. They mixed up all our seats, downgraded few from premium economy fo economy. The crew were not professional, they seem to be in a rush! Also some with an attitude

business class food was pretty average otherwise it was a good experience

Everything OK , except the plane left more than an hour late so I couldn’t participate in an excursion I had that morning in Brcelona

Flight from Madrid to Dakar had no onboard entertainment for a business class. Not even a single screen . That was disappointing. The WiFi only worked for the first 45 mins of the flight.

I paid to upgrade to Business Class. The queue to check in at the Business Class aisle was full of people without Business Class tickets, the fast-track immigration line was “closed” but the representative opened it up for his friends, regardless (there was a lot of fist-bumping), and the lounge was an absolute mess…..4 staff sitting playing with their phones while every table had dirty plates and glasses waiting to be cleared…..and the least said about the rude lady on the reception desk at the lounge , the better!

Great flight, short and good attention. Didn't took any food so can't say thing about it

A 13 hour flight with no food apart from what they offered from a menu you had to pay for. On top of that, there were no blankets, so during the flight when the cabin temperature dropped, everyone was very cold. Neither of these things were highlighted at the time of booking. This is the worst long-haul flight I’ve ever encountered.

Horrible. Paid for seats for my family. Iberia changed planes and never notified us that the seats we paid extra for did not even exist on the plane. We were randomly placed on the plane. Thankfully, we were seated together. Upon boarding, my youngest daughter was pulled from the line and they just arbitrarily changed her seat 7 rows back from the rest of the family. I had to wait at the gate while they tried to see us back together. One of the most uncomfortable small spaces on a plane I’ve ever experienced. When I called Iberia, they first told me that no mistake was made that the plane was never changed. Yet my receipt for my paid seats were for rows that did not even exist on this type of plane we were getting on. They said that they would reimburse my money and I would get an email, but I’ve never received any information or emails regarding a refund for the seats that I had paid extra for. Then when we arrived in Madrid, one of the pieces of luggage that we had checked in was damaged to the point that the handle that was stowed in to the luggage was broken off by the crew members handling the luggage. The crew on the plane was very nice, but as far as the rest of the experience, I would be very hesitant to ever use Iberia again.

Bad business class. Staff totally not helping. Lights and chargers not working

The airplane was old. Some things didn’t work out of middle seat was broken. The rest was OK.

A basic tea/ coffee and a snack could be provided especially for long distance flyers.

Very long and took extra push back to BA staff to get a realistic flight after they made me miss my original direct flight. Eventually landed 9 hours late and incurred many extra costs with other missed bookings

Used to be my "go to" airline but would be my last choice these days. I think some of the cabin crew believe it would be a great job if it wasn't for the customers.

We had to pay extra for seats and bags (even for an international flight). I paid for extra comfort seats, but it was under an overhead bin that the crew used for supplies. I paid extra hoping to get sleep. We were constantly woken up by the crew opening and closing the bins. Our seat shouldn't be considered extra comfort. We paid significantly more than the rest of the cabin for these seats

We found the bag drop/ check-in proceedure at T5 unnecessarily complicated. We paid extra for seat selection in advance and were allocated worse seats at T5. We found the check-in person was not particularly helpful although the the staff at the gate were super good.

There was no legroom whatsoever to the point where my wife dropped her phone and was unable to retrieve it as she couldn’t move. The sound system for the entertainment had a broken socket so was effectively out of action as it just crackled. Just dreadful, I will actively avoid BA in the future

British Airways provided prompt service and maintained excellent cleanliness throughout the flight. However, the business class seats felt tight, and the cabin temperature was uncomfortably warm, making it difficult to sleep. Since I couldn’t rest, I turned to the in-flight entertainment, but the selection was heavily focused on Paramount content, which isn’t my preference. I also found the Bollywood movie options quite limited compared to other airlines. On the positive side, the spirits selection was impressive, and the staff was exceptionally friendly and attentive.

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

1. Missed to deliver bags at Destination 2. no coordination at Layover for flight connection for wheel chair , could have missed flights 3. Customer service agents are not honest , talk with attitude and do not provide correct information about baggage policy
