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.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

There was no wheelchair or wheelchair escort at the gate..unacceptable

Delayed 4 hours because of maintenance issue they knew about all day. Get another plane. Time is precious!

no wifi and the aircraft was very old with tiny 4” screens.

Did not wait long for wheelchair and attendant to arrive after checking in. Wheeled down to plane Was greeted with a smile when entering the plane Choice of snacks was very limited to 2 items. Seats are uncomfortable. My butt was sore after the 1st hour of flying. Needs better cushioning at seats.

Did not wait long for wheelchair and attendant to arrive after checking in. Wheeled down to plane Was greeted with a smile when entering the plane Choice of snacks was very limited to 2 items.

One hour delayed departure resulted in problems with planned ground transportation at my destination.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

No WiFi No TV Bag of chips I guess it could be worse.

Very uncomfortable seats and seat backs, and I am only 5’9”. Delayed due to crew issues, spent a long time with no ventilation. Teeny overhead bins. Wifi worked well. Arrived safely.

Boarding was friendly and quick. While the plane model was older with no live tv, the entertainment was full of movies and tv shows. All food was available. Pilots were very communicative with status of the flight. Flight landed on time.

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

Easy boarding in group 2. Landed 1/2 hr early. Delicious cookie snack.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

Good. The wife was not working but then it got resolved.

Missed this flight due to delays from my previous flight

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

Well, flight times cause some wait, but there were not times available and we understood. I didn't check any luggage, because it has become too expensive. I was able to add any extra items to my co-travellers check bags. [Luckily, this trip wasn't international.] Last, I hadn't flown AA domestically for a while, but partners and coworkers had warned me in advance that not all planes have monitors at every seat. Luckily, I was mostly prepared to use the in-flight entertainment and happy I was. The great: AA staff is always kind and comfort is way better than the budget airlines that I sometimes have to fly. I know my points and vouchers all expired over the last couple of years, but I still enjoy AA when I do fly with them. I also appreciate all of the locations we can go directly from pur home airport. Since we are traveling more now, I hope to take advantage.

Poor on time performance. Flight was delayed due to a lightbulb. No updates from the pilot. Plane was dirty and hot, AC didn't work well.

Perfect flight. On time departure and early arrival. Smooth flight.

It was right on time and crew were very courteous

Charlotte airport is miserable. For American I always have to connect from the end of terminal E to the end of terminal B and the stupid moving walkways are always broken. And the flights to all seem of least importance so they never leave on time in either direction.

Cut off carry ons, had to check, got on and there was plenty of bin space. Disappointing.

Nice clean modern plane no issues with the b flight

Being back games on the in-flight entertainment. Also your flight attendants need a break, raise, or overall attitude adjustment.

Flight attendants used to be nice to people. And any flight over 5 hours should have some kind of food other than tiny pretzels and one drink comped.

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

I was penalized for a mistake made by your team

comfortable flight. not fond of the idea to pay for every little detail. baggage checkin or carry ons, basic snack, or some sort of basic entertainment/wifi. would be nice to offer these as perks and stop with the penny pinching.

They changed our gate 30 minutes before boarding began. We noticed about 20 people missed their flight due to doors closing early.

It would have been no e to have the option of a mid day flight and not super early or super late in the day.

Flight was delayed 2+ hours missed a concert because of it…

Smooth flight flight attendants were extremely helpful kind friendly. I had Glenn he was by far the most outgoing

Flight was late taking off. I think the crew and pilots did a good job. It definitely worked for me. I would fly spirit again thank you.

Never made it to Atlanta due to the horrible policy of having to be at the gate 1 hour prior to departure. I was at the airport and the plane had not left Baltimore, but was not allowed to board.

Was not able to board the flight due to a horrible policy that I needed to be at the gate 1 hour before departure. I lost money on this and the connecting flight due to having to book on another airline. I was flying to Florida for my mother's cancer surgery in the afternoon.

Lack of accessable charging stations, very uncomfortable seats the savings are not worth it when nickled and dimed for amenities that are standard on other airlines

Our flight was on time and unremarkable which I'm grateful for, as it is not the norm traveling these days. Frontier is a low-cost carrier and it really shows when compared to other "normal" carriers. They don't even give you water during the flight. The coach seats are decent, however it was not as clean as it should be. We had crumbs all over the floor by our seats.

Flying frontier reminded me of flying with my family in the 80’s in all of the worst ways possible. From poor customer service to little to no technology. The plane was dirty old and also stuck in the 80’s. From their seatbelts to not having anywhere to charge our phones the seats and the equipment I wasn’t sure if I was being punked or thrown back in time. Needless to say I don’t see myself flying frontier ever again.

4 hour delay because they used our aircraft to fly a different segment (per the captain)

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

They lost my baggage on my connection flight, it’s been 24 hours since I put my claim in and still no update on my bags.

As per ultra-low-cost-carrier model, you must adjust to a minimalist approach (or, pay-as-you-go mentality) when evaluating Frontier. That said, here's the pro/con of this trip. PROs Pricing. Incredibly cheap: $30 roundtrip(!!) PDX-PHX. Hard to complain. Schedule: Direct both ways. Pilot made up time and we got in 15-20 mins early each way. Aircraft. Frontier flies Airbus metal, and the aircraft are pretty new. Seating. Airline status-match got me upgraded 'Stretch' seating (their premium economy). *Excellent* legroom. The leather trimmed seats were adequately comfortable. Some of these upgraded seats have recline (this flight did not), and larger tray tables. Compared to standard Frontier economy, which has very tight seating, and ridiculously small tray tables, it was quite nice. Aircrew: The flight attendants on both legs were top tier. Experience, confidence, and customer service skills exceeded what I have seen on the legacy carriers. This is not always true with Frontier, but this team was exemplary. Food-for-sale. Frontier offers no complimentary snacks/bevs except ice water. Purchased a cheese pack and it was adequate and about as expensive as you'd see on a legacy carrier. CONs No power at seats. True on all Frontier flights, but a bummer nonetheless. Bring a battery. No inflight entertainment. Load your own offline before flying. No wifi available. Honestly, with Frontier's upsell model, it still surprises me they don't equip their planes for this and use it as a revenue stream. Heck, for a $30 rt flight, I'd probably have paid $10-15 each way for wifi + movies. Overall, you know going in about the CONs of the carrier model, so really the complaints are minor. I had a day trip to Phoenix for a $30 flight. Great value.

I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people

The flight was delayed and I had to cancel because I would have missed my connection and there were no other flights for the next two days. They also lost my bag!!

They didn’t bother to restock the plane before we left, so most items on the menu were not available.

they charge too much when you arrive in the air port
