I didn’t like not knowing my seat till I got to the airport - and my boarding group was F (last).

I didn’t like not knowing my seat till I got to the airport - and my boarding group was F (last).

My boarding pass birthdate was printed incorrectly causing me to spend an extra hour in a check-in and then again TSA line and to miss a chance to have dinner pre-flight. My window seat was given away and was replaced with a middle seat. I would have liked an opportunity to charge my phone and take advantage of movies but many of the departure gate chargers weren’t operational and I don’t know of an in-flight charging option, The flight left 45 late after trouble with unruly passengers, and I was glad staff removed them.

Horrible. I likely will have to spend several thousand dollars to rebook my international flights, due to their delays, plus a hotel in SF. I can’t wait to never fly them again!

Quick easy boarding. Airport was unprepared for early landing and we were waiting in the plane for 20 minutes before getting a gate.

It was so easy to board using my boarding pass on my iPhone, and I liked what I was given on the plane for food and drink, and everyone was very friendly.

dont re-route to San Jose. Re-route to closer airport. Provide shuttle bus to go to SFO, not just LYFT vouchers.

Staff seemed genuinely nice, not just going through the motions.

I would have rated the entire experience much better were it not for two things: 1. There was inconsistency between what we were told once on the plane vs. the answer I received to the question about "spreading out" from our assigned seats because the flight was sparsely populated, and the entire row we were in was empty but for us. I asked about one of us moving over one seat to make more room for us; before getting on the plane, I was told we could, which seemed like a sensible answer. Once on the plane, it was announced that we needed to stay in our assigned seats despite all of the empty space in our row, which seemed unneccessarily restrictive. 2. To add to the discomfort, we sat on the tarmac once the plane landed in Burbank for over half an hour waiting for a gate to become available. During that time we had to remain seated and buckled in, which was becoming more difficult as time dragged on, especially for my wife. If all of this was due to regulations, that may mitigate the sense of "needless" restriction somewhat, but it points to a need to make regulations less restrictive where it is not appropriate for the current conditions. The crew was not "nasty" about the restrictions, so I do not resent their actions, but it certainly would have been a much more pleasant flight if we had a few more options when it comes to comfort.

The seat side plug ins didn’t work in my row, and I ran out of things to do since my iPad and iPhone ran out of juice. The flight attendant offered me a free drink but I don’t drink. I suggested a free snack box instead and she just shrugged and walked off. Why do us non-drinkers get the short end of the stick?

Flight left two hours late with no real explanation and they inexplicably had the heat running on the flight as well

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

They were an hour late and they didn’t have my wheelchair for me

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

The 1st class male crew member was very pleasant - the short female with round glasses , maybe in 50’s had no personality- never spoke when delivering my food, drink, & never smiled the whole trip! In fact looked annoyed when the boarding proses was happening- I would never hire this woman - unfriendly . Have never dealt with a crew member like her-

5-hour delay due to storms in Tanoa and airspace restricted by Miami traffic controllers.

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

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.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

The flight was short. However, my bag was delayed and was put on another flight.

Flight attendant was incredible. Very efficient, friendly and pleasant. Patricia was one of the best I have ever seen. Please give her a big raise!

LIT to DFW - 3 hours late; the entire plane had been boarded before they told us there was a delay due to a weather-related ground stop in Dallas. DFW to MAY - 2+ hours late due to A/C needing to be repaired after everyone had boarded, then when we finally reach the runway, the First Officer timed out and we had to taxi all the way back to the gate and wait for a new one. I arrived in New Orleans 5+ hours later than I should have. Return flights were completely cancelled; rebooked through the app to fly through CLT instead of DFW. MSY to CLT had no issues, but CLT to LIT was delayed 1.25 hrs because flight attendants had not arrived to the airport yet. At least they didn’t make us all sit on the plane to wait for them. I should have driven.

Tray table was filthy when I sat down. I needed to have someone come clean it because there was food and stains on it WiFi didn’t work after paying for in-flight WiFi. Food was terrible and was not filling at all Chicken was rubbery Flight attendant had an attitude, interrupted me and wasn’t able to answer basic questions about the food selection such as “does the chicken have red sauce in it”. If your flight attendants are not going to know what is in the meals so we can make an educated decision based on dietary restrictions, they shouldn’t be on the plane. My 1.5 year old niece was sleeping and dropped her binkie. I went on the ground under the chairs looking for it. It was at that time that she came up to me as I’m CLEARLY on all 4s with a flashlight and said “I need to get by”. I said one moment please I’m getting something from under the seat (while my head was literally under the seat). Her reply was “no you need to move now” and proceeded to almost push me out of the way. I looked up and all I saw was her toes under my eyes. When I looked in front of me, her private parts were inches away from my face. I then made a comment “you couldn’t waited 2 seconds?” and her response was, “no I need to use the bathroom”. I understand that and would never want to be the reason someone couldn’t get to the bathroom but I was under the seat. She could’ve gone around the other way instead of harassing me, basically placing her private parts on my head and borderline pushing me out of the way. You don’t pay that much for this deplorable experience. This was by far the worst experience I have ever had on American. I will be absolutely thinking twice and thrice about flying American Airlines again. I would rather pay more to fly delta because at least I know their WiFi will work and their flight attendants won’t have a shitty attitude for no reason, nor will they act the way this woman did. Unacceptable.

Liked - nothing. Disliked - delayed 35+ min sitting on the plane. Caused me to miss my connection in Charlotte. American Airlines is the worst US Air Carrier company with atrocious customer service.

Worst situation ever! I booked my tickets for this trip on Alaska Airlines. I guess AA is a partner and we flew nonstop from Eugene to PHX on an AA jet. I had to pay for luggage from PHX to EUG. And this was an Alaska Airlines reservation paid for with Alaska airlines credit card! Got to the PHX airport and was not able to check bags because of some weird issue with the AA software. My reservation had to be the-entered by the agent. I will never pick another American Airlines flight on the Alaska Airlines website. While on vacation, I tried to upgrade our seats for the trip home. The request just buffered and never went through. I tried four times and was charged four times on my credit card. The card was charged but the seats were never changed. What a wreck!

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

I like the boarding process, it was fast. The seat doesn’t have a TV for a long flight and food wasn’t served, just snacks.

Use planes with TVs on flights over 4 hours. The free entertainment was a cheap in between solution for a very long flight that you don't even bother providing meals or decent snacks.

Even though we left CMI late, we mostly made up the time.

I arrived 1 hour prior to boarding, and they said I was too late for a domestic flight. First time I heard that :-(

Check in online was easy. Seats aren’t very comfortable

Fecal matter in seat back pocket. Presumably from a kids diaper.

Worst airline to travel with. They treat you like a prisoner in a jailhouse barking out orders and threats. Nickle and dime you to the same price or higher than a respectable airline like one of the big 3 . Might as well fly with standard airlines

Well I mean u get what u pay for so 🤷‍♂️

Over an hour delay in departure but I was notified beforehand. Another delay on tarmac upon arrival at LGA. We ended up departing the plane almost 2 hours later than expected

I fly Frontier because it’s affordable. I understand that the seats are tight and not the most comfortable…but that’s part of it. The problem with this flight was that there was a group of travelers directly behind me at the back of the plane who were ridiculously loud and obnoxious the entire flight. I’m pretty sure they were drunk and I could periodically smell an odd odor that I believe was one of them using a smokeless vape pen. The stewards had to remind them to keep quiet during the pre-flight instruction, but that was it. They never said another thing to them for the rest of the flight. It was a miserable.

I checked a bag because it was $5 less than carry on. They managed to lose my bag on a 2.5 hr direct flight! Frontier has no airport staff at baggage claim to help. As soon as I got home around 11 pm I tried to use their online system to file the claim for lost bag - system wouldn't take the # on my baggage claim ticket - said it was not the correct number. Also said that I had not checked a bag, which wasn't true - even my online boarding pass showed that I had checked a bag. Wasted about an hour on that process with no luck. Tried again in the morning - same thing. So tried online chat with Frontier bot - waited 35-40" twice to be connected to a baggage agent and it never happened. Eventually drove to PDX after work and waited 2 hrs for the Frontier ticket agents to arrive prior to the next Frontier flight out of PDX and FINALLY got some help from one of them, to take me to lost luggage area where I was able to retrive my bag. Probably took 4-5 hrs. of my time and endless frustration to get my bag. This was my first -- and LAST -- experience flying Frontier Airlines. Check-in was also extremely difficult and time consuming. The flight itself (and staff) were fine but everything else about the experience was a total disaster! The fact that Frontier literally has NO WAY to connect to a human voice for customer service (in this case for lost luggage) is the WORST!!!!!

Frontier is a crappy airline nothing about it is honest

I didn't get to do this flight l, hard to review
