I got a bit sick on the flight, and was so grateful when the male flight attendant explained to me they keep the back row open for cases like mine. He took such great care of me! I was incredibly grateful.

I got a bit sick on the flight, and was so grateful when the male flight attendant explained to me they keep the back row open for cases like mine. He took such great care of me! I was incredibly grateful.

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.

Exceptional. The gate crew responded quickly and got me onto this earlier flight as the final passenger, saving me more than four hours of wait time for my reserved flight.

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!

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

Okay, not wonderful. Short flight. Wi-fi didn't work properly. Stuck waiting for a gate to open upon arrival for 20 or so minutes.

The flight was delayed about 20 minutes, but this was an evening flight, so it comes as no surprise. This flight came a good 1.5 days ahead of hurricane Helene which was still far out in the gulf. However, the flight never removed the seated buckle light. The staff announced from the beginning that due to the bad weather (I suppose the hurricane a day and a half away) they would have to do an abbreviated service with water and a snack. I am fine with their water and snack offering, but this was one of the smoothest flights I've had in years. If Southwest believes a flight like this requires everyone to remain seated, then all of their flights should remain buckled for the entire flight. I cannot help but wonder if things like this are a sneaky way to cut back on expenses since the airline is currently under a lot of pressure to reduce costs.

Although the flight was delayed, but the crew was amazing. They did the best they could to make the time enjoyable.

My experience was find with Southwest. The only issue I have is...at the exact time for me to check in...I don't understand how I always end up in C.

Love Delta. I'll take connections to stay on Delta even if another airline has a direct flight.

There was overbooking that delayed boarding. Then an airport emergency lockdown that caused further delays in boarding. However the time was made up during flight and there was a minimal delay in landing. Everything else was excellent.

Sat in the plane at the gate in SLC for 2+ hours before take off, getting me home nearly 3 hours later than planned.

Really hard to tell what was happening after my flight got delayed five times

I’m on this flight every other week. Same flight, same day of the week, same time of day… Multiple times there are issues getting flight plan registered and FAA approved r to take off. PAPERWORK This is exhausting and it sucks.

Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Flight delayed due to ground hold. Republic airways did a great job.

The flight was smooth, the crew was great but the plane was quite old

Flight was warm for first few hours and quite rough

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

- delayed because video screens not working - delayed getting a gate at DCA Just continued bad experience IAH to DCA.

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

No water or beverage was provided. I had to ask for water. The sole flight attendant had more interest in selling the credit card. In addition when we got to Dulles the plane and gate were misaligned and it took at least 15 minutes to get off the plane.

Flight was delayed almost an hour because the cleaning crew broke one of the bathroom doors.

When we boarded we were treated with care and it never stopped. Got towels before breakfast and after snacks was a lovely touch!

Awful!!!. I do not recommend United. The flight staff are unhappy and don't attempt to make the passengers feel comfortable or welcome. The food is not edible, and the seats are miserable. My expensive luggage was destroyed, and the ticket prices are too much for the experience.

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

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.

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 😏

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

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.

It took 1.5 hours for maintenance to sign off on a repair that was completed the night before. When we landed in DC we had to wait 20 mins for a gate. As a result I missed my connection. American seems to be reducing the number of ground ground crew and causing delays. This us not the first time.

The delays were not communicated well at all. I was in the airport for over 9 hours with little knowledge of if I was actually going to reach my destination.

Seats are very comfortable but WAY too small...i'm only 5'11" and 170 lbs but i barely fit in the chair! Food is just abysmal. I don't even bother eating. Staff were very professional, boarding was smooth, and plenty of room in overheads.

As per usual for my flights with American Airlines, One flight was very delayed and caused me to miss my connection and they moved my flight to another day. I called customer support and was moved back to my original day but different flights. My layover flight was delayed by an additional 30 minutes while the flight crew confirmed that the plane was airworthy. Ultimately, it is less hassle to drive 10 hours than to fly 6 hours with American Airlines. I recommend my friends and family to hitch hike over taking this terrible transit.

My flight was delayed close to 10 times over the course of the evening. I was originally scheduled to depart at 7:03 PM but did not leave until 12:33 AM, resulting in over 9 hours spent waiting at the airport. The only explanation provided was that the aircraft kept being swapped, with no clear reasoning as to why. Weather conditions at both DCA and Tampa were clear, so that was not a factor. The only accommodation offered was a $12 food voucher, which was entirely insufficient given the length of the delay. Overall, I was completely unsatisfied with this experience. A delay of this magnitude with no meaningful communication or accommodations is unacceptable, and I would have expected much more from American Airlines in terms of customer care.

if it's a mobile only entertainment experience, please provide a place to hold the device in the back of the seat.

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.

Horrible experience upon landing. Probably more due to DCA utter incompetence than AA.

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

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