Don’t fly Frontier. They refuse customer assistance and scam people on checking bags.
Verified travelerFlew with Alaska AirlinesPDX-SJCDec 2023
The people who find your lost bags will call you, so always label your bags! They also have separate offices. Their service is great too. Just make sure to set up transportation from San Jose when landing if you have somewhere to be. The Uber drivers and Lyft drivers are extremely bad at speaking English, and will often not even take customers who try to engage them, even if you schedule or give them cash. There are shuttles for around the Bay Area, but they can be a pain if you do not have 25$ in cash. I was a little late to San Jose. Alaska lost a free checked bag. I left it on the plane, and then I managed to leave it at the airport after barely catching a shuttle. Well, I caught a ride with two people and a Uber driver. I was going to split fares, right? Well, the Uber driver and I had so much in common and she felt so sorry for me, because I did NOT make it to SFO in time....that she offered to have me stay with her husband and her. I did not want to invade her space at all, so I had her drop me off at SFO. She didn't charge me! Nicest woman I ever met. I ended up staying overnight like she warned in SFO, because the airport doesn't have restaurants or anything that stay open overnight. I was hungry and planning to get something. I didn't get a chance to, because another airline, United, isn't as organized and doesn't care as much. They just told me I missed a flight and the next one I'd have to see if I get onto unless I bought a standby ticket. Which I did. And they told me the Gate changed 4 different times, and made me stay in line for no reason. I just sat in one place for a few hours. One good thing about San Jose is that they do have restaurants, places to sit adjacent to the restaurants, and the different gates, in a very clear layout. There are also clearly posted hours. PDX is very fancy but not very clearly marked in some ways. SFO is an open layout and the gates are clear but there are also points you can't get past. In PDX, you can also rent a car. Both places have large complexes for cars.

Go first class or choose another airline. At least I will.

OUr pilot was very good and also a good landing in a very gusting Phoenix. Most important.

OUr pilot was very good and also a good landing in a very gusting Phoenix. Most important.

Although both planes (flights) had mechanical issue delaying both of my flights, the crew members handled everything with ease. Both flights had the smoothest take off and landing. I opted to upgrade my seat to first class and really lucked out getting the seat at the very front of the plane. Awesome treat to myself. I really enjoyed my flight.

The staff from check-in counter to the flight crew were great. Flight was right on schedule. 10/10

Changed flight from San Fran to Seattle Then with a Delayed takeoff barely made my connection Waited over an hour for luggage 😜

Very comfortable - thanks. Only small criticism was the delay in disembarking caused by the passengers in the front two rows chatting to the cabin crew.

Probably one of the best flights I’ve had! From entering the airport, to boarding to landing.

Plane had a maintenance problem two hours into the flight and we had to turn around. Alaska was nice to put us up in the Hilton in LAX but the cost of food in the city was WAY higher than our vouchers and the hotel had no continental breakfast. We ended up spending over $100 on food for our family in addition to the vouchers.

Delays, delays, delays.... (and) Told no room for carry on after boarding B Group and told to drop off our carry on at door to be checked in instead. There was plenty of room left in the overheads above our seats right up to the end of boarding!!!!

Wonderful! The Alaska call center representative was really helpful. I accidently made a mistake of picking a flight option for another day. She was extremely helpful. My daughter had a nose bleed during the flight - the crew helped with an ice pack. I wish they had checked afterwards.

Arrive on time cause the TSA can be quite the project. Besides that your trip will be awesome.

It was a perfect flight in all aspects! Both legs!

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

It was really nice! I appreciate the gate attendant allowing families with small children to board early on in the process… that was very helpful! The internet service didn’t work with the app I was trying to use even though I paid the $8… other than that it was great! Oh and I should’ve asked for the whole cranberry cocktail can. That cup was about 2 sips…

I will be flying again Southwest Airlines. Friendly crew, comfortable and affordable.

A bit rush for transit. Food and entertainment are not available

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

We arrived early and finally made it to our gate almost an hour after.

Worst airline ever! The guy weighing my bag had his foot on the metal plate and when I called him out on it, I got this stupid little smirk. La is a scam and so is Spirit Airlines. All the flight attendants looked like they hated our flight just as much as we did.

Unclear pricing; ended up being charged an extra $52 just to get onboard

Spirit is awful. Too expensive for what you get. Stop nickel and diming.

would be great to get basic water, soda at least and stop charging for carry ons

Your crew is a representation of your Standards and Values. The crew from Seattle to LAX, was very disappointing. The crew was more interested in hanging out at the lobby area. Talking, laughing loudly and eating all the snacks. They did not do regular rounds to see if customers needed anything. This was a huge disappointment. I will no longer be flying with your airlines moving forward.

- flight attendants not very friendly. - Paid for WiFi and plane didn’t have it working , never got a refund.

We got to fly on the new airplane. Much better as it’s roomier and cleaner than before. Most Importantly it’s much more comfortable. I still can’t move the seat back but the extra space made up for it. I didn’t taste the food or drinks because they charge for everything so I didn’t bother. I didn’t experience the entertainment because I downloaded my own movies on my phone. The crew was great. The flight itself was smooth . No complaints.

I was comfortable because I upgraded. I would not have been comfortable in economy. It was a short flight so there was limited food service and no inflight entertainment.

I thought since I upgraded my seat I would get some perks. Free water, free snacks. Free carry on luggage.

It’s ridiculous to pay for carry-on luggage. I also wasn’t given an option to specify I have carry on bag at time of ticket purchase. I also could not specify I have carry on luggage at time of online check-in.

The reps working at the airport counter were dumber than a second coat of paint.

My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

It was a short flight so no food or entertainment….

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!

Everything went as planned. Crew was great. Seats were still not that comfortable.

No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.
