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!!!

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

I understand the delays caused by the storm, but that doesn’t mean the systems had to be chaotic. The app showed one thing, the screens showed something else, and the gates kept changing every 10 minutes. It was a nightmare trying to figure out where to go.

Multiple delays due to weather in Chicago, but the crew did their best to get flights rescheduled and on to their destination. I felt like the crews handled a frustrating situation very well, kudos to them! I was very glad to not have a cancelled flight.

Southwest’s point to point system caused a 2 hour delay due to the crew being late from their inbound flight. Also, the WiFi and entertainment didn’t work on the plane.

One, we were met with more than six hours of delays with no information flowing from the airline to the passenger. I had to continually refresh for updates to departure time - which changed multiple times throughout the day. Updates were never pushed to me nor was an explanation provided for the delay until this morning. Two, while they claim that "due to the short flight" no beverage service would be provided. Our flight was mostly empty. I'd think given the massive inconvenience, SW could have shared a Diet Coke and some peanuts. And BTW, SW used to always make these available on this flight back in the day. Let's be honest, this is cost savings at the customer's expense.

Despite paying for an ‘upgraded’ seat in row 1, I had to put my luggage in the middle of the plane. Snacks were bleh and seat was small and uncomfortable and I am not large. Attendants were fine but not super helpful. Plane just seemed outdated.

It was the strangest thing. The flight attendant (who was not very friendly) took our drink orders and then never brought them. I’ve never had that happen before.

Delayed for no reason at all originally. Then they said it was due to weather conditions. Communication between kayak and Southwest was terrible because both displayed different delays and departure times for HOURS throughout the day. The plane then had technical issues which delayed us from taking off even longer. Didn’t actually take off until 11:45pm when the original departure time was 7:35pm. I didn’t get home until 1:30am the next day. I was exhausted and pissed off. I am not confident if I’ll fly southwest in the future or use kayak to book.

A) Checked my luggage at the gate but never got to pre board B) if we are helping with checking our carryon and waiting 40 minutes for it we should have some privileges c) luggage took 40-45 minutes to come.. d) I asked for another snack and was told the plane is full.. seriously a small snack

I like the staff members they were super nice and helpful very sweet people :)

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.

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

It was the hottest flight I’ve been on in a long time. The female flight attendants were not nice.

I'm 6' 2" and even in economy plenty of leg room

Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

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

Raleigh to Chicago was OK. The problem was Chicago to Lincoln. Flight was delayed 4 hours. Give them credit for the updates and reason why it was delayed

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

Flight was delayed almost an hour because the cleaning crew broke one of the bathroom doors.

Comfortable seats and good crew. There should be some breakfast options in menu for economy class to purchase Wifi was not working in the flight

First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.

Please stop those idiotic and unrelenting announcements, commercials and stupid credit card drivel. All together about 15 minutes of stupidness that annoys each passenger.

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.

AA changes gates constantly at DFW. I got 5 or 6 gate changes. Fortunately the last few were all in the same terminal. I know DFW so it is not a big deal for me but it is a bit disturbing.

Flight was delayed due to maintenance issue. Missed my connecting flight. Got rebooked in a middle seat when I had a first class ticket.

It would be helpful to be able to download an eticket from either American airlines or Cathay Pacific; not just Cathay Pacific.

It was OK, but it was delayed about an hour, and my luggage didn't arrive till about an hour and a half after the flight

First no airplane at the gate because the previous flight was canceled (and they didn't know?) Then we board and there's a maintenance issue. Then we're told the technician doesnt have the right certification and they need to call another. Then FINALLY we are taxiing. But wait! Flight plans expire after 3 hours and we were not granted permission to take off. So taxi was halted while a new flight plan was filed. Then....no beverage service. Never flying American Airlines again. If they mess up operations this much, how good can their maintenance or training possibly be?

First class snacks - stewardess gave out multiples to everyone until there was almost no selection left when she got back to me last in first class cabin. Nothing left that I would eat.

Uncomfortable, not managing boarding process and managing people in the way waiting to board at a later time. Terrible delays

Nothing went well. The crew timed out, they sent us to 7 different gates, my original flight got delayed 8.5 hours, and the best American could do was give us a $12 food credit.

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.
