The seat was comfortable, but I paid for upgraded seats and they did not state that there was no outlets for devices.

The seat was comfortable, but I paid for upgraded seats and they did not state that there was no outlets for devices.

My experience was significantly impacted by problems in Seattle with luggage check-in. Apparently, Alaska Air was significantly understaffed in this area for the number of passengers for that morning or they had issues with the machinery processing and loading the baggage. Upon tagging my suitcase, I was sent from one drop-off area to another and yet a third on a different floor. The line to do most of this was VERY long and moved quite slowly at first--I just barely made it on time to catch my flight even. though I arrived at the airport an hour and 40 minutes early. Then when I arrived in Charleston, my bag didn't arrive on the carousel with other luggage and I had to spend extra time tracking it down.. The relative who helped me out at SEATAC said he had never seen the airport so backed up and he travels out of that airport frequently. It was a very stressful experience, and very disappointing.

Eva Airlines attendants were wonderful. I really enjoyed the hot meals. They always greeted me with a warm smile. I'm looking forward to flying back to the USA with them again!

Flight was cancelled which destroyed the rest of our journey.

WOuld have liked coffee or pretzels but other than that, crew and pilot and flight were great. Seat was great, too.

The overhead storage was already packed full when I boarded (I fly peasant class), but the attendant played some Tetris and made a spot for my small suitcase. Thanks!

all crew, pilots and attendants were fantastic. Both to and from flight to SEA, attendants went above and beyond.

I was totally disgusted at the stewardesses supplying the three passengers in front of us in the exit row with multiple rounds of booze. They were loud and inappropriate using profanity to share stories. Our 3 and 7 year old he’s d it as well. Just flat out inappropriate and amazed AA wasn’t implementing a drink limit policy.

Spent extra to choose my seat. Found a window available so grabbed it. They did not mention the row didn’t recline. Had over 5 hour flight stuck in a straight back chair. Traveling for funeral - needed to rest and couldn’t get comfortable (row infront of exit😒 should have realized but wasn’t thinking I guess).

Our Alaska airlines flight eas cancelled 2 days in a row. They did nothing to sccomodate - no hotel rooms or meal vouchers. We were left on our own. We switched airlines to fly home. I would give this serious consideration before using this airline again.

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

I am still at the Airport! Delayed Delayed and Delyaed

The landing was the worst I’ve experienced with a flight.

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

All good on Delta's part. Passengers could be a little more courteous to each other.

The pilots were good. Disappointing when planes don't have electrical ports

No complaints - left 20 minutes later than planned but still arrived on time.

Great experience, boarding was fast and efficient, so much so that we arrived to Chicago very early

Comfortable seating POS to IAH. Food options were satisfactory. Good seat from IAH to ANC. Food options could be better.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

Flight was delayed 5 hours. Updates kept changing. Sears were extremely cramped. Very little leg room. Flight attendant was rushing through with drinks and hit me in the knee either the cart and didn’t apologize. They gave a 15 dollar voucher in airport which doesn’t buy. Much and it was so late that choices were limited.

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

Awful. No counter attendants. No dinner offered due to delays.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.

Upgraded to first class. I would consider the first class on that plane to be only slightly more comfortable than coach. Long delay.

How is it that every American flight from DFW to IND is significantly delayed? This is the third time in two months I have been delayed flying out of DFW - ALWAYS for a maintenance issue. Makes me want to drop flying American altogether…or maybe flying through Dallas. Miserable experience.

Luggage took too long go get off plane in Knoxville. Was almost 45 minutes after the flight landed.

Very turbulent flight, no drinks, very little service, unorganized boarding, gate changed multiple times

Poor seat in rear of aircraft Food at Admiral’s Club Terminal D at DFW inedible

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.

Multiple gate changes and significant delay leaving DFW. Made for a late arrival

For the price of the ticket you get nothing. The plane had 1 bathroom in the back and when the flight attendant did service no one could use it. No announcement just was told to go back to my seat. Ridiculous and rude.

In-flight Wi-Fi didn’t work and the flight was 25 minutes late. The Embraer plane I was on was pretty old and the tray table was broken.

American Airlines no longer has Bischoff biscuits. This is intolerable.
