Delayed for three hours. This seems to be CAL’s MO when flights aren’t filled until they fill it. Business class is nice but not luxe like other airlines. Lots of space and amazing staff.

Delayed for 3 hours- little to no communication about this and staff moves in slow motion

Caribbean airline sucks… they have a promotion to bring 60lbs in your suitcase.. meanwhile when you reached your destination (JFK)… your suitcase didn’t show up. They had too much weight so the suitcase was left in Guyana… like WTF????? Stupid promotion.. just like the uneducated people working with the airline. The representative said there is nothing she can do about it… will not use them again.

Boarding the flight was smooth and the flight was not full so i had an extra seat essentially

There was no flight. They canceled the flight with no knowledge to me, and I still haven’t received a refund

Overall, it was good. There was no food or entertainment, which is why I put poor (it wasn't an issue though).

Nothing, they could have made some accommodation for an awful experience. Me and my family were not informed properly we we separated. They took me off the original flight i booked. I booked our flight at one price and called me and told me they were not honoring my rate and they charged me double of what I paid. Me and my family don’t want to ever use your services again.

This flight was great. The plane took off and arrived at the destination an hour early. The crew was pleasant. The food and entertainment options are minimal but adequate for a 1-hour flight. They passed out water and quickly supplied me with a fresh magazine since the previous one had the crossword section filled out.

Better movie and tv selections. Also, the overnight flight to Trinidad from Toronto, the staff were not very attentive. I did not see them for at least half the fight. They were behind their curtain a lot of the time, and they did not check on us before landing to make sure all landing requirements were met.

Little space for luggage and the flight was delayed by an hour.

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

On the return flight, flight attendant Britt went out of her way to inform passengers that several of us had tight connections.

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Staff at the check-in counter were friendly, happy and helpful. They tagged our bags and sent us to “bag drop off” but were not very clear about where that was. The airport was busy we headed off in what we thought was the right direction until a gentleman waved us down and actually came after us. He was the baggage handler for Delta and recognized our “deer in the headlights “ look-he brought us to the right area (which was marked as the Southwest Airlines Drop Off) and sent us on our way. Wonderful guy, low key and working with a big smile on his face. Loved it. Loved him.

During the flight, the only refreshments provided were crackers and soft drinks; no substantial food was offered despite the international route. Furthermore, our initial flight was delayed, causing us to miss the connecting flight in Atlanta. The airline did not hold the connection, and we were informed that the next available flight is not for another 24 hours. While I am aware of alternative options via JetBlue, they operate out of JFK, which is not a viable solution for us as a resident of New Jersey.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

The flight was delayed 90 minutes The Gate was wrong The Restroom on Aircraft was not clean There was a half used water bottle in my seat

Delta is always a wonderful experience. A clean plane and the crew is really friendly.

Just a bad day to fly. Flight was delayed from scheduled 6:50 pm departure to 8:50 pm. Combination of factors mostly related to weather at the destination airport (which is where the incoming flight originated) which delayed the inbound flight over an hour. Once on board, we taxied but had to hold again on the taxiway for 10 minutes or so. We did not get wheels up until after 9 pm. The flight was smooth but about 18 minutes from our destination, we had to hold for several minutes more due to weather at ORD. We finally landed at ORD about 11:08 pm (accounting for the time difference, that was about a 3 hour delay from our scheduled departure time). It felt like we were never going to get to our destination. But the flight crew and attendants were very good. The movie selection onboard was also very nice. Got to watch half of a movie just during our taxi from the gate at ATL due to the delay!

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

No meal service to the back of the plane as it started late or was too slow to get it out before it was time to land.

Terrible, if possible won't be flying again anytime soon!

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.

The business class seat is exceptional. I wish the food is more palatable.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

the entire flight felt off. The crew seemed uninterested and disengaged. The food service was really bad - overcooked, bland, weird food service. They actually woke us up to serve chicken wraps in the middle of the night, after dinner and before breakfast. Made no sense. Ultimately, I was glad they did though, because the breakfast had been held for so long it was inedible. Eggs, potatoes, sausage - all disgusting. We were asked to "honor" the lavatories for premium customers and stay in our own cabin: this was also strange. So people in economy didn't pay enough to use the closest toilet to them??? It's a toilet. All in all, not the experience I have come to expect from United Airlines. The return flight from Paris to SFO was better, btw.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

I was denied a plastic fork to eat my food and was told plastic forks are for paying customers who buy Jet Blue’s food. So I had to make a utensil out of a cup so nourish my body. Like a refugee. Because decency is dead.

I was especially impressed without efficiently the crew got passengers on and off. One of the stewards was slightly gruff, I thought. No big deal but that's what I noticed.

Absolutely horrible. Flight was delayed 4 hours and they had no clue what was going on.

Onboard functioning wide-variety entertainment on a budget and having an open pantry is nice. Seats are not comfortable but go provide plenty of legroom for a 6'2" 260lbs man.

Even though the weather made a lot of flights become cancelled Jet Blue made the flight that was supposed to leave at 9 pm and we left at 12:15 am and I was so grateful- Thanks to the Senior Jet Blue Staff who made those decisions

Worst customer service ever experienced on the planet, dirty plane, no communication, and severe delays

Flight cancelled 2 hours prior to boarding. No explanation. No refunds.

Delayed by 1.5 hours. Terrible apologies, half hearted at best. It will be a LONG time until i book w Jet Blue again. Very disappointed.

My check in was stressful. I somehow lost my seat from my original booking, the plane showed no availability/no seat when it was time to check-in. I called and was instructed to try to get a seat at the airport. I asked if it was a full flight and the travel agent said the site showed some seating but was not able to secure one for me. Why not? On my way to the airport the app finally revealed one available seat towards the back of the aircraft that I was able to book. It ended up being an overbooked flight, so glad I wasn't stuck.

Flights with JetBlue from San Diego to Boston are a miserable experience. The flight was delayed about 1.5 hours due to “weather” supposedly but the flights for other airlines left on time so it just have been some kind of weather that only affects JetBlue. I had a small carry on - purse. The crew stored it in a bin 2 rows down from me because they were using the bin next to my seat for other people’s stuff. The TV screen in the emergency row seats does not work. It just was awful from start to finish. When we landed, we had to sit inside the plane for a very long time because the plane had to be moved to a different gate.

I have never been assaulted they way I was today in Charlotte - shame on American

One of our group members was struggling to walk. In Charlotte we asked for a wheelchair and she was accompanied by Desmond. I was impressed by his patience and attention. In Boston she received the same service. I didn’t get the name of the helper but she went above and beyond in assisting us. A great AA service

Better snacks but flight and crew were amazing on this flight

Found that the plane used for this short flight is smaller and therefore the seats are really squeezed tight.

It was the most un-special flight experience in my life.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

Flight was on-time, boarding was flawless and the crew was friendly.

The staff are very, very professional. It's what flying should feel like.

Flight boarded from Gate 159B, the farthest gate in the LAX Bradley Terminal. While the flight operated on time, the first class cabin attendant made no recognition of my being an Advantage Executive Platinum member.

For an international flight the seats were smaller than most flight I have been on in economy. I don’t know the size of the seats or perhaps it was the size of the seat dividers that made the seats feel smaller and little amount of space to even turn your body if you needed to
