Airline reviews

My experience with Delta started with my luggage being found ripped open with items missing. The baggage office told me to bring the bag, and I wanted them to see how I found it. The agent refused, so I carried my bag into the office myself. The agent was nice enough to fix the zipper and gave me a red card with a number to call. I followed the steps; first one department, then the baggage department took over. This took more than two hours on the phone. The return flight was okay. The flight lead was checking her meals and then asked if we wanted anything before departure. However, throughout the flight, I had to ask for things because she was reading her book;which I have no issue with if she had been more attentive. At the end of the flight, the pilot appeared annoyed with the flight lead for not following his instructions regarding a meal he had requested; a chicken sandwichand said, "I asked for that for the flight." On the positive side, my work event in Vegas went well, and now I'm home relaxing.

Awful. There was an unexpected delay of nearly three hours because there were not enough flight attendants. I understand this is likely due to FAA regulations; but in that case, Delta should coordinate with smaller airports such as RDU to have extra flight attendants on the ground and "on call". In addition, this was the second 2-hour+ delay to Boston on this route in one week.

It was strange that the flight attendant was so adamant about having phones turned to airplane mode that he was calling out names from networks shown and waiting until they were all gone. I've never experienced that before, and after already working through an hour+ delay, it felt tone deaf. I take dozens of flights per year and have never experienced anything similar.

Flight was delayed multiple time and for more than 1 hr. My onward flight from BOS to MCI was also delayed. These delays have caused me so much inconvenience and Delta does nothing to ensure flights take off on time. No one knew why the inbound flight was delayed and what was the issue.

This flight was originally delayed by ~45 minutes; which is fine. However, there were additional delays due to late offboarding of the prior flight, unclear issues with the boarding process, delays on the tarmac, and exceptionally long taxiing. None of these issues were communicated proactively. Additionally, the flight had exceptionally rough turbulence, which led to a very uncomfortable flight and no traditional beverage service. Again, this is understandable, but it was not communicated up-front by the flight team.

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

If you cant travel Delta One, Comfort Class is the next best thing!

Arrived early, comfortable seats (Comfort+). Mediocre food, poor wifi (intermittent).

Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

My flight yesterday evening was delayed 3.5 hours with no water or food service. Poor experience

I missed my flight and had to buy new tickets Rome- Boston

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

Super friendly with lots of drink options an entertainment. Friendly crew.

I like flying first class, and United has a nice one

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

I was forced to check my carry-on backpack despite there being space - but it came out on the baggage carousel so fast it didn't even delay my pickup. Otherwise a good flight. Boarding began early (which was disadvantageous for me) but fine.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

Check in and passport control were seamless and efficient. Plenty of room in overhead bins. Our original seats were separate but crew at the gate put us together in finer seats. I also had left my phone on board and the Jet Blue staff were so helpful in retrieving it after I had left the baggage area

Flight was delayed. But my finances flight with JetBlue a week before same route was extra delayed and then cancelled at 2am when his flight was suppose to take off at 7pm was never provided a hotel or anything. Came back to airport and his rescheduled flight was cancelled again for 2 days later. Was told since it was a weather issue they don’t do refunds. But that’s a lie because I booked him on another airline at the same time and they were able to take off perfectly fine

Separated a pair of family members(father and teenage daughter) on all legs of the flight that were booked together, just to create an upsell. Food was horrible and only catered to vegetarians and gluten free crowd. I’d rather give more of my money to another straight shooting airline.

A nightmare. Scheduled flight delayed 2 hours then cancelled because pilot timed out . Unable to find another pilot. Really?! Weather certainly a factor, but JetBlue seemed totally unprepared for the chaos that ensued when flight routes were cancelled. More cancelled flights, finally many of us who had been bumped from other flights were allowed to board a Boston bound plane around 3:00am, delay after delay, sat on tarmac for another half hour while pilot dealt with weight distribution issues (?), arrived in Boston 4:30. Crew were wonderful- same attendants all day and night and they were exhausted. Fortunately for me and my son that Boston was our final destination, not so lucky for many who missed connecting flights.

The flight was delayed 14 hours and communication was very poor. No one seemed to know what was happening and the gate agent was trying to help people for several flights. She was by herself trying to help 100s of people.

For whatever reason, I could not check in online. Kept getting the "It's not you it's us" message. Even when we tried the kiosk at the airport - same results. The check-in person had a very difficult time getting our boarding passes together despite the fact that we could show confirmation on the jetblue website. After a very long time we finally got boarding passes. The only other issue is, my vegetarian meal featured chicken.

JetBlue worker, Blythe, was so amazing at the DCA counter. If it wasn’t for her, I’m not sure we would’ve made it through. Please thank her!

The flight out was delayed from 3:40pm to 5pm and again to 8pm. We boarded after 5pm, had to disembark because they could not get the Engine started, then we switched gates and got a new plane and did not board until after 8pm.

This was the first flight I've taken since pre-pandemic. I was pleased with how orderly the boarding and disembarking went. The seats were comfortable. I loved that there was no "first class'. The attendants and passengers I met were all very friendly and welcoming.

we were delayed because of some safety check that wasn't done or available

Frontier line changes my flight schedule with out my authorization. They never ask me and with out my concern they cut off 4 hours of my vacation they force my to leave 4 hours early from Puerto Rico.

Good- no snacks on a 4+ hour flight is painful but more painful was the lack of WiFi.

I guess you get what you pay for. The seats are very uncomfortable and very little space. The snacks were pricey.

Flight was changed (according to Frontier, by Kayak) without my notification. And all flights were delayed by at least an hour and a half. Uncomfortable plane. Bad service. Will never fly Frontier again.

Charging $74 for one checked bag is outrageous. I will never fly Frontier again.

Was left with many other passengers in SJU by frontier airlines due to delay caused by frontier. Worst experience ever and worst airline ever.

It was horrible. My plane was delayed until the next day resulting in me losing a day of work. It’s absolutely unacceptable and I won’t be flying with you any more and I will strongly caution others to avoid your airline as well.

When we arrived we lasted 48 minutes to be able to get off the plane without air and the plane turned off more than half of the passengers because after they started to leave they realized that the bridge was defective

Pro: The stuff was great. Friendly, patient and caring. Our seat row was clean. The bath room was clean. Our flights were close to on time. Con: The leg room is too small. No blankets or pillows. No entertainment devices at all. I can’t remember to have a food choice. I would fly again with frontier for short distances.

Great option to American Airlines. Affordable prices when compared to AA. Prices in AA to and from Puerto Rico are like Fly Emirates to Kwait.
