There was a loud squeaky sound the whole time we were flying.

6.0 GoodEliza, Apr 2024SAN - LAX
Read more about Delta reviews

There was a loud squeaky sound the whole time we were flying.

Seats in first class on the E175 recline too far back. I was in 2A, and the man in 1A fully reclined almost the entire flight. It took 6-7 inches of space away from me and made it very difficult to work on my laptop.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Mario was great. Made a night flight on a small aircraft pleasant and memorable.

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Quick flight on older aircraft. Sat in last row…really noisy. No video available

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

I really liked the way snacks and drinks were available throughout the flight!!! The flight attendants were also all fantastic!

Best Thing flight took less time than programmed, quick entry and exit. Recommended!

Always like Jet Blue! It seems, however, that people are getting bigger & seats are getting smaller! We had a very full flight and I couldn't get an aisle seat like I always do. I wish there were more leg room. People sitting next to me were very nice though so it was fine to disturb them if I needed to use the restroom. Otherwise the flight was fine but a bit long.

For some reason, the seats on this flight seemed unusually uncomfortable. Speaking with friends who took another JetBlue flight later in the day, they brought up the same issue.

None of the in flight Direct TV worked. A better selection of Shows would have been better. The baggage was s low. Otherwise we enjoyed our flight!

The service was very good, will use the airline again.

the staff was very helpful and the airline was very good.

JetBlue has really gone downhill. They have all the problems without the discounted price. If you need to get anywhere in time, this is no longer the airlines for you

Seat was surprisingly comfortable and roomy. I like the onboard “pantry”. Lavatory was kept very clean.

Flight was delayed 30 minutes, but otherwise was terrific. We used our points to upgrade to Mint for the first time which was a fun & comfortable. Josh & Kori were very attentive & genuinely cared about our comfort.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

Packed in like sardines, very uncomfortable. Sitting the aisle my shoulder was rammed into numerous times by rushing flight attendants. Also flight was very cold.

the head jack on my seat didn't work and the power outlet didn't work for my seat

Left 2 hours later for delayed I had to take care a kid with special need since people don’t want to move to accommodate the rest of the family. . It wasn’t bad but that made me upset that people can be that selfish.

For a 22 minute flight all you expect is for it to be safe and comfortable

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Wouldn’t let me check in said couldn’t find a ticket had to wait very long Time

Cold air blew constantly on my legs almost making me numb.

On the new 319 NEO? seatback entertainment system did not work even when the flight attendant rebooted it. At least I had my cell phone to connect with wifi.

The flight was fine. All the delays and poor communication and customer service were the worst! We were supposed to arrive in London at 7:10 am. In stead we arrived at 1:30 pm. And now American Airlines refuses to make things right but only sent a canned apology after I contacted customer relations.

The flight was delayed for over four hours due to “maintenance “. Your ground staff made no efforts to avoid my family missing their connecting flight to London. They did not try to reroute them and didn’t even offer meal vouchers without being asked. My daughter, her husband and four children were in the States for our son’s celebration of life service. They experienced rude and unhelpful staff in Asheville. The lack of communication was disgraceful. They missed their connecting flight and the first rebooking. Then the 2nd rebooked flight was delayed by over two hours. They didn’t leave Charlotte until 1:30 AM. Since returning home my granddaughters sleep has been so disrupted that they are overly tired and cry hysterically at bedtime. I have already contacted you regarding compensation but have yet to receive a response. All I’ve received is a canned wrote response. This is not acceptable!!! When my wife and I traveled to England in December on your partner, British Airlines, we were delayed for 4 and one half hours. We missed our connecting train to Leeds and had to pay double. They not only reimbursed our extra train expense, they also refunded half our airfare. And upon our return to the States we were surprised to find that they had upgraded us for free! Now that’s customer service!!! I look forward to a prompt real human response. Sincerely, Jon Cannon

No complaints. The flight was uneventful, which is a good thing.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

Generally good but we were delayed almost two hours from the original time of purchase. The pilot claimed an internal issue then an external equipment issue that needed to be adddressed. He made up a lot of the time.

Flight was delayed until Next day as crew timed out

I was able to get on standby with relative ease

Everything went well. Got a snack and a beverage.. Able to watch live tv and movies in flight

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

Terrible. Seats are bad and the baggage policy is inconsistent

Better than I expected but I did pay for a seat and carry on bags ahead of time.

I hope to avoid flying with them in the future. First flight got cancelled then got stuck with a 13 hour layover in Denver. The process was long and frustrating to many people.

Flight was delayed on the runway for 40 minutes the crew did not even offer even water to passengers to compensate for the flight delayed. The flight was delayed due to aircraft mechanical issues. Worst customer service ever

The flight was delayed and I had to cancel because I would have missed my connection and there were no other flights for the next two days. They also lost my bag!!

My first time to fly Frontier and loved it! Boarding was super easy as we only had personal items. Crew was helpful and funny and the plane was clean. Pilot was also great at landing the plane smoothly.

late late late late no accountability no refund no adjustment no reasonable solution
