FAQs - booking Idaho flights

  • I'm traveling to Twin Falls. Which airport do I fly into?

    The closest airport to Twin Falls is the Magic Valley Regional Airport, just 10m from the city center. But keep in mind that this airport is only served by flights from Salt Lake City International Airport, which means that if you're traveling from another city, you'll have to account for a layover. Alternatively, if you prefer to choose from fewer flights but want more airlines and routes to choose from, you can fly into Boise Airport or Friedman Memorial Airport.

I volunteered to let them put my carry on suitcase in the baggage storage area. But when we landed I was told it was being unloaded IN A DIFFERENT TERMINAL! I had to walk (painful for me) a long way to retrieve my bag and my ride had to move from the waiting area they were in to a totally different one. Not happy.

I volunteered to let them put my carry on suitcase in the baggage storage area. But when we landed I was told it was being unloaded IN A DIFFERENT TERMINAL! I had to walk (painful for me) a long way to retrieve my bag and my ride had to move from the waiting area they were in to a totally different one. Not happy.

Over 2 hour delay for a 50-minute flight is unacceptable, especially in normal weather. Very poor communication via app

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

They delayed our flight by 45 minutes and then re-updated the departure time back to normal schedule with no notification, email, or app update causing probably 40 people to miss the flight as they left without us.

Som delays but overall we almost made it on the original time.

They put me on a chair in between two men, one overweight who was almost falling on top of me, and the other was even uncomfortable because I was half falling because of what the other was pushing me. I stayed with. my feet were swollen from fluid retention and from being unable to accommodate myself. it was very uncomfortable. I asked for help but they told me that the flight was full and they couldn't help me. I got off the plane almost unable to walk due to the inflammation. and then at FLL airport I asked for help because I couldn't go to my next flight, which was a connection.

The walk from baggage claim to the taxi is very difficult for older people I will never fly into JFK again. It is physically challenging

Overall fine but both ways for this trip was delayed.

Flight was delayed by almost 5 hours. Suitcase was not loaded despite the flight being near empty (my colleagues’ suitcases did reach JFK, unlike mine). Had to argue on phone to get JetBlue to deliver the case to my hotel. Never again

The flight was excellent. The crew was welcoming and attentive.

At least the delays were short. Business class, even in the new planes is very crowded now with crappy tray tables

There were issues with the first segment but what really bothered me overall is that you rebooked me and put me in a seat away from my wife and then put her in another booking or boarding group. I don't like having to monitor every little thing you guys do in order to get what I paid for in the first place.

See my previous comments. I was probably booked in business but was moved to economy

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

The new Airbus A231neo has neat tech but the economy seats are so tight together that I always had my shoulders against one passenger or the other. I was very miffed that Basic Economy REQUIRES check-in of bags other than your personal carry-on; if you want to offer low-cost airline prices and then add services for a fee, just let me carry on my duffel. Hell, I could have put my carry on IN the duffel and called it a day but the gate agent would not let me; I ended up paying $40 for the risk of losing my bag. Not the worst flight, but far from the best.

No water on the toilets, dirty sits. 4 hours delayed departure.

Boarding was efficient. Crew was not pleasant and skipped me during a round of beverage service. Older plane with no seat back screens and I couldn’t connect to wifi or their entertainment offerings.

My flight was delayed for a whole day, so I lost a day of my vacation.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

The American flight was a connecting flight to an international flight. The international flight has a 2 check bag rule. Despite being informed of this, American would only check 1 bag and wanted 100 to check the second (basically a 3rd carry-on) to NYC. Subsequently tsa took a sealed container of maple syrup and a few other things that couldn't be in carry-on plus I had to lug around 3 pieces of luggage for the entire trip. The American reservation was made with the international and American actually checked the one piece the entire way to China. This is one of the reasons that I will avoid American airlines if possible in the future.

I arrived to LaGuardia Airport 50 minutes prior to my 6am flight but was told that I was too late and would have to flight standby to Dallas in order reach my final destination of Jackson, MS. Hundreds of people were in my situation but the agents chalked this up to being normal for any day. Had my been able to board my original flight I would have arrived at my destination by 10:30am. I didn’t arrive until 7:30pm which included a 30 minute wait on the tarmac. Strangely my luggage arrived at my final destination at 12:30pm of the same travel day. This was by far the worst travel experience I’ve ever had.

delayed multiple times. no resolution on anything from AA customer service. was put on hold in chat to talk to manager. was 6th in line to talk to manager for more than TWELVE HOURS - from sometime around 9AM until well after I had gone to bed that evening. no explanation, no attempt to make it right. just a five hour delay because of repeated maintenance claims

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

It was freezing in there. When I asked about it, the response is “we would have to tell them” and then she just walked away and continued to serve beverages. Everyone was cold and they didn’t care at all.

I did not enjoy continuously being lied to about the amount of time we would circle Chicago before deciding to redirect to Milwaukee. Then the amount of time we would sit on the ground in Milwaukee waiting for gas, or to take off again. Or the amount of time it would then take to get to Chicago again, or sit on the runway waiting for a gate. The whole time continuously hopefully we would make our connecting flight that kept getting delayed as well. Only to scramble and miss it. Enough with the BS. Tell me the truth. "Sorry, things are backed up and your probably not going to make your flight. You should rebook on the next flight now rather than wait." You'll never hear those words from an airline. Speaking of which. If the flight has been redirected and/or is seriously delayed, how about making the WiFi free for everyone so they get to rebooking and reserving hotel rooms while still in the air. You've inconvenienced me already and now you want me to pay $20 for Internet so I can try to make other plans. Absolutely disgusting!

The flight was quick which gave me more time to get to my other flight.

16 Hours delayed, NOT because of the cybersecurity Microsoft issue, but because we were one flight attendant short, then when the missing flight attendant showed up two hours later, the flying shift of our pilot had expired, so, now no pilot. American Airlines is the new Spirit Airlines, actually, that is not fair for Spirit, they are probably better.

Worst flight in terms of service and food. Attendants were inexperienced, no preflight drinks, did come and give us hot towels until well into the flight. The left the Curtin open between main cabin and everyone from the main cabin went to the fist class bathroom. Food was awful! Had the golden chicken and was too lemony and inedible. No offer of coffee after. Awful!

Excellent. Attendants served preflight drinks and were courteous and nice.

On a day with 1000s of worldwide flight cancellations, I was worried about my flight. Not only did my Spirit flight leave as scheduled, but it arrived at destination earlier than expected! This made my day!

The length of delays were extremely frustrating. Stuck in airport for hours. We were to get meal vouchers but it was 3 hours until someone responded to me from their WhatsApp and they said wait for an email. Still no vouchers and it’s been 24 hours. Terrible customer service. The ppl at the gates and bag checkin were miserable and not helpful

Spirit airlines is very bad airline staff doesnt know how to treat passangers they didnt allow us in the flight we reached 45 minutes ago from flight departure but they denied nd said you are late Very disappointed i never reccomend spirit airlines

spirt air lines took advantage of two eighty year olds. we paid extra for cancelation due to health reasons they did not honer they have no spirit. I hope they treat there grand parents beter.

Our flight was delayed four hours and staff did nothing to accommodate the issue.

The flight has been cancelled we have been waiting at the gate for almost 2 hours and they didn't gave me an update for rebooking

Would have been better if I would’ve made it on my flight but it was delayed twice and then canceled and now I’m stuck till Monday which was and extra 5 days I did not count on .

Awful. My flight was three hours late leaving DFW and we just arrived at LAX three hours late and stuck on the runway. I heard the Spirit workers at the desk in DFW say that we were waiting on a crew. I am extremely disappointed in Spirit.

Delays and sending me to different terminal for departures. It looked very confusing and disorganized

Canceled my first flight for no discernible reason and couldn't rebook me on to a new flight until the next day. They did not compensate me for the delay in any way.

Better than expected.on time. Friendly staff in NY however MYR not so nice.

The flight crew and flight attendants are poorly trained and demonstrate poor professionalism. They have a sloppy appearance and communicate with patrons poorly. It is embarrassing for them to be representatives of an airline and for them to be called professionals.

After 5 hours of delay, they cancelled the flight. Very disappointed

My flight to LA was cancelled. I waited at the airport for 3 hrs saying it was delayed and then all of a sudden it was cancelled. Frontier only gave me a voucher and refund but could not rebook me. Flights on other airlines were too expensive last minute. I had to drive down to LA and didn’t even take my return flight home since I had to drive. One of the worst airline experiences in my life. It’s crazy how airlines can just upend people’s plans just like that.

Flying Frontiier was extremely poor!! I paid for a7:15am flight on flight 1601 from PHL To Las Vegas and the delay was brutally, excruciatingly and disgustingly long (8 hrs). I arrived by Uber to PHL at 5:30 am and had to spend the entire 8 hr delay inside the airport. Even more atrocious was that the flight was delayed twice. On the phone with customer service for two hours and was not fully compensated. I feel taken advantage of with this airline. They offered a menial couched for another flight within 90 days to me and my husband who has never flown but this experience has made us almost 100% sure to not fly this airline and will suggest that others don’t either. We don’t want to book ever again, don’t want a menial voucher and I believe by standard and because the flight was delayed for 8 hours, I should be fully reimbursed for the entire round trip. There is no excuse why this should have ever occurred. After sharing my experience with others in Vegas and Philadelphia, I was told that Frontier airlines is notorious for long delayed flights, poor customer service and refusal to compensate people correctly. I’m very nervous to see what departing from Vegas to Philadelphia will bring.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Flight was 3 hours late leaving. Poor communication from the staff about delays. Impossible to get in touch with customer service (by design). And it actually didn't come out to be much cheaper than a non-budget airline! Not worth the headache, I'm never flying Frontier again

I’ve never flown frontier without a flight getting canceled. I understand that things go wrong with planes, but all other airlines handle cancellations so well. Frontier becomes a dumpster fire if a problem appears for them.

Checking in was easy and simple, crew was nice and efficient, but I would improve seat assignment randomness to make it easier to sit together based on when you check in. Overall would fly with them again.

Flying Frontier was a nightmare. From the booking through Kayak, checking in, departing and arriving, I will never recommend Kayak or Frontier.
