Boise airport is quick to get through security and very easy to navigate, so you don’t need to give yourself as much time as you normally would at larger airports.

Since I flew First Class I really have no advice! Everything was perfect! The ticketing agents were fantastic, flew through TSA Precheck, great announcements at the gate, quick boarding. My only suggestion is to check First Class prices before committing to the very expensive baggage fees and choosing a seat fee!!!

It is a ten minute walk from tarmac to baggage claim. If you have mobility issues, it is best to ask for a wheelchair. I did not receive a message on my phone regarding which carousel by bags would be loaded on and there was NOT a centralized notification board to inform you of the carousel

If they ask you to check your bag at the gate because the flight is full, you get to board sooner even if you don't check ALL of your bags.

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

Boarding process of asking for volunteers to check bags goes against the system you had before with 2 bags checked free. This process is more of a guilt trip than a caring attitude toward the customer. In addition bag-size scrutiny has increased which also slows down the process of boarding. My wife said she will not fly on your airline again unless there is no other option.

Eveeyrime I fly they are begging for bags due to cabin overhead space. What they should so ia take the bags that are clearly too big to fit wheels first on their side. And those of us who give up the bag should really get their bags first. When boarding, nobody wants stupid jokes about how hot it is on board. Give us some cool air. Im usually sick from the heat by the time we take off.

No wifi, seems to be very common with Southwest currently. Everything else was normal.

Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

Friendly crew kept coming by to make sure all was ok, provide additional refreshments, etc.

It was good. Last flight was delayed but I always say that is in God's plan

Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.

Overall good, just screaming kids in the area the whole flight.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

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!

Snacks for our toddler could have been better, front the standpoint of variety but that’s not any different from other airlines.

I fell asleep and missed my flight and they rescheduled me no problem. Staff was professional and the plane was clean. I was very happy with my experience.

I enjoyed the Starlink access but didn't have much time to use it. It also kept dropping me so I gave up. The food was very good though when I asked for a different "dessert" they didn't have anything. Chocolate Brownie Cookies are not suitable for everyone...maybe children. The flight staff were amazing - at least in First Class! My first time ever! The trip from Boise to San Diego was FAR better than going to Boise.

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.

My experience with Delta started with my luggage being found ripped open with items missing. The baggage office told me to bring the bag, and I wanted them to see how I found it. The agent refused, so I carried my bag into the office myself. The agent was nice enough to fix the zipper and gave me a red card with a number to call. I followed the steps; first one department, then the baggage department took over. This took more than two hours on the phone. The return flight was okay. The flight lead was checking her meals and then asked if we wanted anything before departure. However, throughout the flight, I had to ask for things because she was reading her book;which I have no issue with if she had been more attentive. At the end of the flight, the pilot appeared annoyed with the flight lead for not following his instructions regarding a meal he had requested; a chicken sandwichand said, "I asked for that for the flight." On the positive side, my work event in Vegas went well, and now I'm home relaxing.

Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.

The ac must have died, it was way to hot on this flight. Boarding g was chaotic. The flight was delayed for boarding. Not a great experience.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

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.

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

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.

Other airlines were canceling flights but Delta got us home. Crew was friendly and professional. It would have been nice to have had a little more notice about the delays because we had already arrived at the airport when the first of several delays were communicated but I understand that storm forecasting isn’t simple and we were grateful that Delta didn’t just cancel the flight.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

On time departure and early arrival. Kind and professional service from flight crew

Flight staff and all was fine. Food always sucks on planes so nothing new.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

My flight was delayed so bad i missed u it so i just said never mind

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

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.

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.

The flight was delayed 4 hours, and when we finally boarded, they told us that the fuel was only just then checked. So, we waited even longer to take off.

Great. Clean. Seats comfortable. Food was free. Had new release movies.

The airplane I love and I love I came back safe thank you American airlines

Although there were two delays, they were communicated clearly and the boarding process was expedited. The crew was pleasant and efficient.

The flight I booked was conveniently timed, had one brief stop and was going to be quick. The flight I ended up getting was delayed, took longer, had a far longer layover and arrived hours later than planned. Thanks for nothing.

Flight attendant made the flight very enjoyable. He was courteous and gave great care to the passengers

Everything was done like clockwork and I find no fault with the airline.

This flight 1810 on 7/30 from EWR to DFW got 4 hours delay. this round trip experience is bad, my AA flight 618 from DFW to EWR on 7/28 was redirected to PIT and totally delayed about 9 hours due to mixed of weather and AA IT outage and then on the way back delayed for 4 hours. Lucky, i changed my flight to UA on the way back. i don't like AA anymore. i will consider other airline options in the future.

Bad experience going to DFW with an IT outage then bad on the way back with a nearly 5 hour delay that’s started as maintenance then caused us to wait further due to weather - which would not have happened if we had left on time.

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.
