It was great and arrived home a little sooner than expected which is nice.

Stop asking fir people to check carry on and then bind are free. Then the wait to get your luggage is ridiculous. This particular flight came with a 45 min wait, after waiting in tarmac waiting for a gate inhaling jet exhaust. And how about those landings?! Do the pilots not know the earth is coming up under the descending plane?! This is the only airline I get sick on. Every. Time.

Multiple delays due to weather in Chicago, but the crew did their best to get flights rescheduled and on to their destination. I felt like the crews handled a frustrating situation very well, kudos to them! I was very glad to not have a cancelled flight.

The flight was delayed due to earlier issues at other airports. The crew was excellent & made it a good trip.

I'm glad it wasn't only 75% full because I could get a good seat

We waited in the airplane for over 45 min for a southwest employee to make the flight. This cause over half the plane to miss their connecting flight in Denver. When we confronted the desk upon arrival, they told us the only flight they had was the next day leaving at 8:50 pm!!! Or they offered to get us to Burbank or LA, but after that we were on our own to get back to Santa Barbara. I paid for a flight from sba to bna bna to sba. My re entry into mom mode has been 💯 rough because of southwest mistake with my flight. And now I’m leaving to Reno tomorrow for a vballl tournament and just discovered that my leg in Vegas has me and my 3 kids on a stand by flight even though I had booked these ticket last year November!! Do better southwest!

I flew twice this week on Southwest, was delayed over 2 hours both ways. From Pittsburgh to Chicago it was due to weather but the gate agents, pilot etc were great at updating everyone. Today from Midway to Pittsburgh the plane had come from an international location, kept getting delayed, no information was given until we were delayed for the third time. It was ridiculous, whoever scheduled that plane to fly to Pittsburgh after didn’t consider a lot of things.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

The crew was very nice and respectful and everything went well.

Having a direct flight between Pittsburgh and Austin makes traveling so easy.

The main issue was the quantity of the drink. The hostess gave only half cup full of the soft drink. I was thirsty and was expecting full glass like every other time.

The baseline is to have everything happen as expected. That is what happened with the small exception that climate control in the aircraft sss not turned on when boarding started making the aircraft very hot. All in all great experience!

The crew was excellent but the entertainment did not work. The 3mm jack for the headphones was faulty and no sound was available for entertainment.

Very aggressive at the boarding area of only allowing one person passed a line/ sign

We were delayed so pilots can rest and had no WiFi the whole trip. First class seats are small compared to other planes

My flight home from Knoxville, TN, included a layover in Atlanta. I boarded the aircraft in Zone 5 and although there was limited overhead space, I was able to put my 'backpack' style roller-bag above my seat. Unfortunately, due to continued bad weather, we had to deplane. There were many people who would have missed their connection, so they rebooked. When we were re-boarding, the gate agent welcomed zone 5 and then made an announcement: All roller-bags for zone 5 passengers and higher will need to be gate checked. I promptly pushed the telescoping handle in and held my bag like a backpack. I was able to bring it on board, which was a relief. Upon entering the aircraft it became apparent that there was easily 40% open overhead space. There were audible signs of angry passengers who felt duped into checking their bags when in fact there were noticeably LESS passengers on the aircraft and TONS of overhead space. I'm not sure what kinds of parameters are used to determine when to cut off roller-bags from being brought on board, but it seemed deceptive and underhanded to have so many people get stuck checking their bags when clearly there was ample room for at least one more zone.

The CRJ-900 was clean but the overhead air vents were broken in our First Class row, making the cabin very hot until about 30 mins into the flight. The flight attendants were both extremely apologetic and accommodating though so that is why I rated the flight as very good. They checked on us many times and truly showed they cared. The snacks for an hour and a half flight could be better. Would be nice if there was a small plated meal over convenient store snacks. WiFi also was not working. And it would be nice if Delta had adjustable headrests on these planes.

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

My easiest trip ever. Flights left on time, and came in a few minutes early. The flights weren’t full so it was very comfortable. Thank you United

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

Even though we were delayed, we were able to make our connection

I still prefer Delta, but Delta doesn’t fly to State College PA.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Nothing bad to say about the actual crew or airline. It was nice to have a complimentary FULL can of soda, as well as a snack. Blankets and earbuds were also provided at no cost for this red eye flight. I especially appreciated the free WiFi and movie selection with the Bluetooth option. It helped the flight pass more quickly. No matter who you fly, boarding and disembarking are always SUCH a pain. As I mentioned, this is on the passengers and not the crew!!

Ok so apparently the new policy on United Airlines is that customers in the main cabin should NEVER be served more than once and besides picking up trash there should NEVER be another interaction with the customer for any reason.

Terrible. We needed to change return flights due to an incoming hurricane. They would not refund our return flight.

The employees at Sioux Falls airport were friendly and helpful. As a veteran/retired military Allegiant allows two checked bags, one carry on bag and a seat on the plane all at no cost. The flight crew and pilots were friendly and very competent.

The check-in and flight crew employees are excellent. The flight was good and the seats were adequate.

The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

It was a dismal experience. The flight was delayed for 4 hours, and we spent hours in the plane, without air, during the summer. We were not provided with water, and the medical assistance was inadequate when it arose.

The landing the pilot was very smooth. The flight attendant was kind of rude.The boarding the plane in punta Gorda was not great made us wait out in the heat 😞

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

No food is available without purchasing it and there is no in-flight entertainment. Both of these are OK because we got an inexpensive flight from Allegiant and, otherwise, our experience was excellent.

Clean, friendly, roomy. But check-in from the phone link was terrible. Repeated attempts wouldn’t save at the final step. Just kept spinning! It was very frustrating. Finally, I used the app (vs website link) to check-in which worked very smoothly on the first attempt.

Internet is much improved, which is very important to me a s a business traveler. The off boarding of the plane was fantastic. Very quick and very orderly. We had to check our carry-ons before we got on the plane and they were retrieved and available to us very quickly. We left on time and arrived early. All very good things

The flight was overbooked. And the gate agent basically said that the flight will not leave unless two people came forward to give up their seats. Offered money. Raised the $$ too. But we were there for a while and flight was delayed. When passengers approached the gate agent asking what would happen if no one volunteered- the answer was flight would be cancelled! Ridiculous! It’s American’s fault for overbooking. The service level is going from Bad to worse it seems.

My wife has a scooter and they where supposed to send from departure to destination and had it go to connecting flight,not good.Nobody has knowledge of the scooters or the battery's.

Not to have gotten delayed by 2+ hours for the fourth straight American flight. They're the worst.

Did not get any refreshments. Crew was very nice but limited. Small seats

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

I didn’t like anything, being platinum pro get you absolutely nowhere and does not increase the customer service treatment whatsoever anymore. My flight was canceled and they put me on a flight eight hours later that would’ve got me back in the middle of the night. They could’ve easily move me up to an hour Prior on an earlier flight. My second flight was unreasonable to take, the third flight was also canceled due to mechanical issues like the first flight. I don’t know what’s going on with American, but they are falling apart, after seven flight changes I finally got home, Unreasonable.

This was a horrible American Airlines experience, and it discourages me from flying with them again. It may have stemmed from a mechanical delay, but it appeared that the team was unprepared to respond to the delay. After boarding, we waited an hour before finally taking off. After landing at our destination, we waited an additional hour on the tarmac waiting for a gate (at 8:00pm) to be assigned and cleared. The flight crew did their best, but they were clearly tired and also ready to be done for the day. Because of the delay, I missed a connecting flight. It was a very poor experience.

Fantastic! If it had not been for a check-in agent in Knoxville I may have not gotten my passes on British Airways. I couldn’t check-in online because British Airways had messed us the info on my tickets to London & Inverness. AA’s was great! British Airways was a continuous series of delays and frustrations.

Wheelchair was waiting for me,changed to a better seat which was great as it's hard for me to walk
