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.
Verified travelerFlew with Alaska Airlines-Jan 2026
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!!!
Verified travelerFlew with Alaska Airlines-Feb 2026
Dont wear all your clothes its not worth the discomfort to save on a checked bag.
AllieFlew with Alaska Airlines-May 2025
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
LisaFlew with Alaska Airlines-Jul 2024
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.

Different snack. Better coordination between terminal desk and plane for boarding. Stood in jetway for 5 minutes while plane was being cleaned by ground crew.

Different snack. Better coordination between terminal desk and plane for boarding. Stood in jetway for 5 minutes while plane was being cleaned by ground crew.

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

The service was fine, about the same as you get on most lower end airlines. I dont understand the perks of flying them much anymore for the cost.

the flight was significantly delayed. Not much was done by the airline to compensate passengers

the flight itself was totally fine. The crew were great and very helpful. The flight was delayed, however, over an hour without a lot of information as to why.

Had to walk back and forth between concourses to figure out which gate I was supposed to be at. The app and the flight board in the airport had different gates listed. Was told numerous times to check bags only to get on the plane and find that there was plenty of room for bags. The flight was over an hour late which had me landing after the last train departed. WiFi was unusable

My experience was okay I changed my returning flight and I was charged extra money which I dont think should be the case, especially because I experienced small delays from my going flight. And many flights were either canceled or delayed after my original flight time. I believe some customers should have the ability to change flights due to certain situations

I've taken four flights with Southwest within the last three months and every single flight was delayed.

It was great and arrived home a little sooner than expected which is nice.

I fly out every other weekend and this is the 4th time my flight has been delayed at Southwest. I will be flying out twice a month on average for the next 6-7 months. If this is your average ‘on time’ I’ll probably be flying another airline.

WiFi was inoperable - second in four recent Southwest flights where that was true. I need WiFi for work and if Southwest cannot provide, I’ll stop using it

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.

I just wish the boarding process/time to take off after boarding was quicker and more efficient. I also wish that the overhead luggage was managed better. almost every time i fly there is no space for carry ons and they are either checked or I end up having to store it several rows back from my seat. Delta should not offer carryons for all customers if there is not actually space for everyone

Boarding was delayed by an hour and then we proceeded to sit on the tarmac for another 30-40 minutes. No clear explanation was ever given and the delay caused me to miss my connecting flight home. Was forced to stay the night in the connecting city which impacted my following workday and cause personal issues at home as well.

I didn't like like much about my experience with Delta. I had to spend the entire day at the airport due to some mechanical issues. My flight was supposed to leave at 8:30am didn't leave until 6pm. Horrible experience.

Bad. Flight was delayed due to maintenance issue with Delta. Seats were small, no service, bag got broken on initial flight. Cramped and hot. Sitting inside with no ac.

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

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

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

Seats needs to be wirer and food is very poor

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

Was on the plane sitting longer than the actual flight in air was, boarded at 5:45p and didn't take off until 6:50p flight was only about 30 minutes long. Just was poor experience will booking more with American Airlines.

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.

We waitied for 2 hours for flights to take off. Make us to seat 2 hours in small space is not good.

Ultimately fine but plane seemed dated and creaky and landing was hard…. At no time did I feel unsafe so thank you.

Wheel Chair Access sucked. I had a guy from Bangaldesh drop me off without taking me to the gate

The amount of gate changes and delays is completely unacceptable. This has happened on 3 of 4 trips between Chicago and Dallas in 2026.

I didn't like anything about this flight. The only reason anyone drinks Jack is because you ran out of Woodford. You should know to stock more Woodford. When you wait of first class hand and foot from the minute they get on the plane 5 feet from me but then start service from the rear of the plane so main cabin plus gets the scraps, that's how you get people to stop flying your airline.

American Airlines was horrible! The layover flight to DFW was delayed with no clear communication and for us having to stay the whole day which led to staying a night in Dallas was comped with 2 $12 dollar vouchers and a crappy hotel. We missed a whole day in Tokyo for our honeymoon and stressed the whole 24 hours. We were supposed to leave at the same time the following day, but that was delayed hours again. And instead of letting the delayed flight go first, they let the flight that was scheduled ahead of us. American should refund us the day wasted in Dallas that should have been in Tokyo! We had lost out on paid events that we can’t get refunded. When we finally did leave, it was a good flight. You would think that was the only issue with American but we from the LAX layover, we were delayed 6 hours and were given a $12 dollar voucher that covered a drink only. The only communication we were given then was that because they were delayed in a prior flight we were delayed again. I don’t understand why it was only with American that we had such a bad time with! They have definitely left a sour taste in our mouths for our honeymoon! And then they did send an email saying we could have 2K miles…. For what? To be delayed into another day and miss our flight again?

The delay update was very late. I had a stressful short connection and RAN through Chicago to get to the next flight, only to find the plane wasn't at the gate yet an nobody was boarding. I would not have had to run if the delay was updated earlier.

comfy and spacious seats for premium economy, nice flight attendants. only problem was the wifi did not work, and my entertainment screen was locked in Arabic language and all kids shows with no way of seemingly changing it. but the flight was fine and I arrived with no issues

Flight was delayed because of mechanical. Could not get landing space which caused me to miss my connection. Messy and not organized.

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.
