Airline reviews

From Las Vegas to Boise all went well. However, our flight was delayed in Boise and I missed my connecting flight from Seattle to Pasco. Moreover, the last flight to Pasco was full and I was booked on the 11:30 flight Sunday and given a hotel accommodation. However, I was scheduled to deliver the Sunday morning service at my church and needed to arrive no later than 10:00. Therefore, I booked a Delta flight scheduled to arrive in Pasco at 23:09. My piece of luggage checked in Las Vegas arrived in Pasco earlier today. I waited at the airport for over an hour last night to speak with an Alaska agent to no avail. I went back after church this morning in search of my piece of luggage and it could not be located. After waiting for 40 minutes to speak to the agent authorized to take my claim, he announced that he was closing the counter to assist on the flight line but not before providing me with a telephone number that would help me with filing my claim. Before I was able to make the call (due to other factors) I received a call from Alaska agent informing me that my luggage had just arrived and I am now waiting for it to be delivered. I deliberately took the more complicated route home to ensure that I would be home in plenty of time to prepare for myself for the Sunday service and accommodate my relatives’ needs. I believe the airport is undermanned given the number of flights coming in and going out. It was fiasco last night with three flights waiting for luggage and another flight landing within minutes. Today’s problems stemmed from a lack of cross training and a serious amount of cargo/baggage going out and too few people scheduled to cover.

It was ok. First time flying with them to Boise Won’t do again

Our late returning flight was annoying. The plane was small, but it made boarding and disembarking quicker. I do wish they offered a gluten free snack.

I was standing in line to use the restroom. A First Class passenger wanted to use the restroom after me, but Jaques made me wait on Flight 3418 from BOI to SJC on December 12, 2025. I felt this was inappropriate and rude.

The plane was old so the seats were very worn out. The seats were hard, uncomfortable, and caused me actual pain. The lights were too bright. The flight itself was fine.

Flight was delayed but still made it to Phoenix on time. Boarding went quickly, the flight was smooth.

The man next to us had a medical emergency a the flight attendants really stepped up and quickly helped turn a bad situation into one with a great outcome. Brandon, Ranger , and Jose all did wonderful jobs gathering all the medical field passengers on the plane to help (a my husband) and they helped revive the unresponsive patient within a few minutes with juice and oxygen. It was a great example of community and teamwork and I’m so impressed with the staff.

Flight on time. Crew good. Seating Bad. Have to pay extra on a not cheap flight to avoid being next to toilet.

Both of my planes were delayed which is less than ideal but it's alright, unsurprising with very small flights.

Excellent, I traveled with my adult mom, she was happy for your service, especially, because you helped her with the reel chair. Only a little thing, in the airplane to Boise, the seat was very worn.

I have diamond medallion status and usually we are in comfort plus . We were in main this time ( which was fine ) and my husband wanted wine . I have at least 10 vouchers for drinks that are good for this year and next! The attendant would not take the picture of the voucher as proof and never came back to check as She asked me to pull it up on delta Wi-Fi. Instead my husband just used his Amex to buy the wine . Disappointing!!!

Food is basically Sun Chips, cookies or Cheezits. I had an exit row seat so I had plenty of room. The crew was very nice and efficient. Pilot kept us informed. Pretty good flight.

Air travel sucks. It continues to be awful for all airlines. No shame on delta alone.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

Comfort Plus seat 11E seemed smaller than prior flights. The movie selection is good. Watched most of the most recent Tron movie. I'll watch the remaining part later as my movie is saved in the Delta Seatback Experience.

Flight was late from Newark to Atlanta, I asked flight attendant to please let my family of 3 out first when we landed to Atlanta because we were late for our connecting flight to Quito. She didn't and we were late for 5 minutes we couldn't board the plane and spend hours trying to get another flight with customer service for the next day.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Late delayed flight delays boarding and delays leaving and delays on arrival too. Cramped plane no room no food.

DTW line is too long. The flights from DTW to BWI are always delayed for unknown reasons.

Delta canceled our flight and we had to scramble to find another airline to get home. Phoenix is not a delta hub so they didn’t have another plane. It would have been a red eye though Salt Lake City. Getting in at 5am. No bueno.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

left on time, reasonable boarding process arrived early luggage came out quickly

I like flying first class, and United has a nice one

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

The flight was on time and arrived early. The crew were friendly and helpful.

Overall experience was great. Flights were almost on time in departing and we arrived at our destination as scheduled. No issues with amenities or flight crew. Everything went well as as expected. Will fly again with American Airlines in the future!

Boarding was organized and timely. Food was mediocre, especially for first class travel.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

AA delayed the flight for 3 hours and 50 minutes, but delayed the last 2 hours, 30 minutes at a time, so if we knew before, could have stayed at home and worked instead of being at the airport wasting time... The plane's crew was excellent, not their fault.

Liked that it was on time. Staff professional and friendly.

Things were delayed a little. But that didn’t affect my plans. It was fine. I was surprised it was so full thanksgiving day. The crew were friendly and professional.

Everything was good The connects, with no blame to crew. Or pilots. I understand they are short staffed. Everything went well for me. I'll be using you guys again in May if not sooner.

The flight was smooth, the pilot kept us informed about delays and we arrived more of less on time

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

It was fine. Nobody was outstandingly friendly but no one was rude and everything was smooth . The captain thanked us for flying but no one greeted me as I walked on the plane or as I exited which is the least they could do lol

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.

Check in on the web portal was cumbersome! After several attempts I finally got the boarding pass.

Excellent flight and even arrived 23 min early. No entertainment , or wi fi on board, but I downloaded a couple of movies beforehand which kept me entertained. Really like flying Allegiant airlines.

WE were delayed about an hour and never any communications from the employees working the gate. We also were moved to a total of three gates.

I love how they show love to their customers and care about them too.

I liked how when I got on board how fast we ended up taking off but what I truly disliked was how uncomfortable the seats were. There was truly never a time that I could ever get comfortable during both of my flights. The seats could get away during shorter flights but flights 3 hour plus makes it hard to enjoy.

The crew was great and the flight was very smooth. Can’t really judge food since I did not get any because it costs money. The seat was comfortable for what we bought. Thanks!

Crew was great. No entertainment and food and beverage was for purchase only, even water

It was canceled. The flight wasn’t rescheduled, everyone had to figure out their own new arrangements. They said we would get refunded our original fare and receive an additional $150. We received links for $100 only and they expired before we could activate them.
