The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

Everything was on time. I was disappointed by the front section female, African American flight attendant. I did not see her name tag or would have identified by name not race. As passengers moved to the bathroom early in flight, she would say with a disdainful tone “I have to say the seat belt light is on” then go back to her book. Better trained flight attendants say something like be careful the seat belt light is on.

Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

The flight was great. We were not offered any beverages though. And there was no real turbulence, so not sure why.

The crew and everyone on board was wonderful, We had to wait for a flight attendant to come from Orlando to Jax after a sudden illness., We left an hour late and “missed “ our connection.flight. The plane was held for us but we were told that our bags probably wouldn’t make the flight even though we would and would have to return to the airport in Boston pick up our late luggage or choose to fly on the same flight as our luggage. We chose to wait 4 hours on the next flight with our luggage and missed our first day in Boston for our grand daughter’s 10th bday celebration. When we arrived on the next flight, our luggage was sitting in a room waiting on us - evidently it did make out original flight., We were given meal vouchers in Baltimore for our delay which we really appreciated and thought was a very kind gesture by Southwest - sudden illnesses are not their fault., I just feel like we would not have missed an entire day in Boston if you offered more early morning direct flights and /or had offered to deliver our luggage to the hotel instead of us having to return to the airport to retrieve our luggage on the next flight due to a technicality - it wasn't “lost luggage”. Other than that , it was a perfect flight .

Not good.,At first delayed due to weather, then still had to load all the luggage, then a mechanical issue. Upon finally arriving, clothes wet as suitcases sat out in the rain. In a hard side suitcase! Ruined some paper items inside. Not happy!

The flight itself was good. We were delayed 1 1/2 hours which was not good.

Flight was fine but new boarding policy was a drag Xtra time passenger group And Waiting until entire bridge empties before calling a list preferred... Waste of time

Always dependable. No surprises. That’s how I like to fly!

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

Aside from a completely packed plane, I really have no complaints.

The flight was very good and the staff was very friendly and helpful!

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The food is terrible. The staff is wonderful. Comfort is good.

Excellent check-in. Crew was good. Excellent communication from flight deck.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

Flight was on time, the staff was personable & professional, & the plane arrived on time.

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

Horrible experience. They delayed our flight 7 hours!! We had to seat at the airport with kids on 4th July all day!

Flights were on time. Free Wifi on plane. Everything was well organized.

This is for UA2274 from Houston to Sacramento. The flight was delayed arriving due to mechanical issues so we left about 3 hours later than scheduled. When boarding the plane the temperature inside was excessive - likely close to 100. Pilot apologized and said it was going to improve at altitude, which it did. But before that I honestly thought there might have been more delays removing passengers made ill from the heat. We were delayed leaving due to another mechanical issue. There was not water on the plane due to a panel that was not secured. They did that quickly, but the combination of mechanical issues was rather disturbing and did not reflect well on United.

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average, Air canada food was much better than united.

They cancelled our flight at the last minute due to mechanical issues. Rather, they “delayed” it till the next morning. A pain in the neck when traveling with two young children. Crew was really nice, which made up for it somewhat. This is the second flight from delta that was cancelled this year. Definitely going to fly another airline when possible

Noticing spectacular about the flight. It got me fro m point a to b. High priced

- flight was delayed several hours due to weather (understandable) - flight delayed further and we were told by attendants "we are not sure where the pilots are but they are on their way" as we have to find different pilots for the flight - announcements over the PA were somewhat unprofessional by the attendants, seems they need more training and were not reading off the script. They showed their young age and immaturity in their communications with the passengers. They were not clear and lacked professional communication language. - going from a hub to hub we were also parked at the tarmac at ohare for an additional hour and kept being told "few more minutes". Please just let the passengers know the real wait time instead of hiding the truth. We understand there is traffic and weather delays, but we just want transparency. There are several logistics of our lives that revolve around what the attendants and pilots are sharing with us but they are not being transparant.

Requested early boarding to disinfect seat, tray table, etc. before general boarding. Instructed to board after wheelchair passengers. Waited on jet bridge behind 12 wheelchair passengers. Stopped immediately after entering plane to wait for gate agent in rear of plane cleaning a seat that was wet, got to my row and found both seats adjacent to mine already occupied, with the lack of room making it impossible for me to clean my own space and defeating the purpose of my boarding early. Cleaned the armrests and tray table as best I could.

The new planes (American Eagle) are beautiful and especially comfortable. The flight attendants are consistently professional and courteous. And, while it may seem inconsequential, the new liquid tube of coffee creamer—in contrast to the powdered coffee creamer—makes all the difference in a cup of coffee.

Crew at the gate was very crabby and not at all polite. The plane was very hot the entire flight. And the seat cushion was very worn out.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

Delayed 4 hours from Charlotte to Nashville. Could have driven there faster. Information provided by AA was sparse.

Gate change was a little tough but it was a good flight otherwise

Great flight, great service but most of all- our luggage made the trip with us.,

Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy

The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve

This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.

Severe turbulence. Captain never came on to reassure passengers after things settled down.

The crew was delayed because they came on another flight that was delayed due to weather 10pm flight left at 1.30 am The airline made no effort to align alternate crew

The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.

After waiting several minutes to be acknowledged by 3 employees on their phones, was told we had missed our flight because the doors were closed at that literal moment. Had they given any actual service or help while we were standing there we would have been on with time to spare. More than 10 people were turned away in this fashion claiming there was no way they could let us on the plane, even though it was still sitting connected to the terminal. After the desk agents let us know they didn't care about the situation we were forced to pay more than twice the price of our original tickets as no credits were given for the price of the "missed" flight. And the icing on the cake was after being treated poorly, fleeced for another few hundred dollars for new tickets? We waited on the next plane for 25 minutes passed the "doors closed" time, letting almost an extra dozen passengers on board. You're company has lazy, disinterested employees and your lack of any real help will ensure this was the first and last time we fly Frontier. Awful.

Frontier notifying me earlier of flight delay of over 2 hours.

The trip was unremarkable which is good. Crew was very professional and courteous.

Good for the price. My only complaint is that the pilot should keep the air flowing while passengers are waiting to getting out of airplane.
