Aircraft, flight (except for late arrival at gate) and service

Pilot announced we would arrive early in Seattle. When we go to Seattle we waited 30 minutes for a gate and actually arrived late. When we got to baggage claim we had no claim area posted for our flight; another 15 minutes waiting to find out where our luggage would be

Crew was friendly and responsive. Gate crew kept passengers informed of the delays. Flight itself was ok.

Flight ETD was 8:25 but plane developed a mechanical problem. After about 20 minutes waiting for maintenance the Captain decided to go back to the gate for fuel and repairs. After maintenance came on board the decision was made to deplane. Finally, a plane from Chicago was scheduled to take us to San Diego. After boarding at about 12:30, it was discovered that catering never loaded food. We waited for over an hour for food to be delivered. At close to 2pm the Captain, who kept us aware of what was going on, asked us if we would agree to leave without a full delivery of food, and all agreed. So by 2pm we were finally enroute to San Diego but having a seat in the back meant we only got to eat what was left, which for me, was a small cheese pack.

55.00 for a carry on bag?? Are you kidding me? If I had known that when I bought the tickets of course I wouldn't have bought the tickets. For another hundred dollars I could have bought a ticket From Alaska flown in comfort and had free water !!! Instead I had to use that 100.00 for carry on bags! I hate you guys! You're the biggest rip off. I fly an average 3 times a year. I will never fly Spirit and I will tell everyone on all social media not to fly with spirit unless they enjoy getting raped!!!

The trip was generally as expected. This was the first trip our family of four had taken since before the baggage fees had become common. I chose this airline for its price. For a short flight, this was very nice. It is best to know your luggage needs before you purchase. It was helpful to see the total round trip pricing as well.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
