Slow boarding, limited food and drink portions. Bad delays and turbulence

The entire travel day was a disaster from beginning to end. Woke up at two in the morning to make it to San Juan airport in time for a 5:30 am flight to Milwaukee which connected in Baltimore. Massive delays lead to me missing original connection out of Baltimore. Sixteen hours of delays/rebooking/layover time later, arrived in Milwaukee to find that only one of two checked bags made it there (despite the fact that Southwest brought another 737 jet to San Juan to fly us out to our original Baltimore connection—-not squeezed into another booked flight). The flight from Baltimore to Milwaukee was barely half full, so there was no logical reason to ship my bags out of Baltimore on a different flight to Chicago to then ship to Milwaukee. Southwest decided that my bags should not have been on the same connecting flight I WAS ON to Milwaukee, and then proceeded to accidentally leave my larger bag with the important items in Chicago. Terrible logic and support all around. Extremely angered and disappointed with SW. What a clownish operation your company has become!

3 hour delay. Had to change plans and was still delayed.

As always, the entire Southwest experience was wonderful, from online booking to flight to baggage retrieval. Very grateful.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I used to fly SWA all the time. I know the crew has their little acts that are often fun, and entertaining. On this flight one of the crew was just not nice. Very surprising.

The flight was delayed for almost an hour. We sat on the tarmac. There was no announcement. Not by the pilot or the crew. And for some reason, there was no beverage service, so even though it was a short flight, we had sat on the tarmac and the extra hour delay made me understandably thirsty. Water would’ve been nice if they had offered it. And for the first time, I forgot to bring my own water bottle. Reminder to bring your own water bottle because you never know if you’re going to get a beverage.

Flight delayed four separate times. I’m now one hour hours late to landing.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.

Awesome! On time flight, early arrival, and a complimentary upgrade!

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Our flight from SFO to MSP was right on time on 11/15/2025. No delays. As we approached MSP at about 8 pm, we circled in the air until 8:40 pm so I don't call that efficient for MSP. I think the captain should announce the delay and why. (as if we all don't know that we are just circling around the area, slowing down, speeding up, slowing down.) Thank you. Marilyn Fischer

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Wifi did not work and they only served water, coffee, or tea.

Had assistance at airport getting from arrivals gate to departure gate; I couldn't have managed without that extra help. Thank you Delta.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

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.

No screens or meal options. Freezing cold. Dirty seats. Left late.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.

Boarding was again a "free for all". We were boarding group 4, and almost the entire plane was able to board before us. It's a shame that someone who follows the rules, gets the short end of the stick. Not fair.

It was perfect! I've never flown with United before, but I definitely will in the future

They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service

Deplaning was delayed because of Jetbridge equipment issues in MKE, causing an issue on an otherwise great flight.

The plane was spartan, the seats not that comfortable. It was like flying a super low budget airline. They charged for coffee!!! I have never, ever experienced that before.

I had no problems but the changing of planes that I was supposed to be on was confusing. Maybe it would be helpful to let people know your flight changed. Not everyone understands airports or how flying works.

Flight was delayed multiple times without giving any particular reason and the only thing that was communicated was that 'Aircraft is getting ready'. I was stuck at SFO airport for 15 hours and finally took Southwest Airlines flight back home to Dallas.

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

there are no options s for snack besides cookies would ve nice to have a salty option n

it was fine, decent flight... dont get food besides cookies or pretzels so not sure why you ask about food. same for entertainment..

this plane was really old, had exit row seats and tray was in arm of seat so super uncomfortable to use. another seat they could t even use the tray it was broke. seat i. front of me had duct tape on it cause seat was ripped open... this plane should either be updated or retired.

Very poor delay in dfw was really bad n long

I didn't like that my paid for seat was changed 2 hours before my flight.

The gate changed over 6 times in the 4 hours before this flight having us walking all over and back again. The agent told me that the American app and the airport monitors are not reliable and I should Google the flight number for accurate flight information! Shocking tip but the gate still kept changing anyway and then the flight was delayed an hour because of another maintenance issue. Not a great experience.

They didn’t offer a water, even after I asked

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.

I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.

It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.

While booking it was not obvious that I had to pay for carryon. Realized it only during check-in. Overall, meh!

Stop changing gates at sfo. When you are elderly going back for it’s not fun.

After 5 hours of delay, they cancelled the flight. Very disappointed

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline

Flight was cancelled and I had to spend the night in the airport lugging my suitcase around
