Let's see - I was in first class. The flight itself was fine - and only one hour + late!

Food - Served the "breakfast" (when it was called a protein plate) I had coming (into MSP). for "lunch" on the way back (called it a meat plate for lunch. One slice turkey, one slice jamon, one egg, cinnamon roll and fruit. Just because they don't want to serve bread - they call it a protein plate? I'm not on a protein diet. Food was pretty sick for the amount I paid for the fight. Stewardess said it was against Republic's rules to give a customer a can of tonic water (so I could add to the small amount of vodka) - she also told me that it was against Delta's, American's and United's rules to give a can - strange? First Class seat did not recline. First Class was freezing per every flight on this segment (the stewardesses sit in the back and don't want to be uncomfortable - if they make the front warm - the back is too hot for them (not joking on this one). So many things to list - that I will finish on the AA site.

Everything ran smoothly on this flight. No delays before, pleasant staff, great entertainment selection, okay food options, working equipment (e.g., tv in the headrest worked, seatbelts worked, lavatories were operational, etc.). This flight met all my expectations

The only hiccup was the wait time on the runway before take off. Not sure if that was the airport’s fault or the airline’s fault. We must have waited 45 minutes.

Flight wasn’t full

I had to re-purchase the same ticket I already bought because I missed another flight on the same itinerary, they cancelled this leg of the trip for me. Spirit will rush the planes out so they have a better on time percentage and regularly leave many passengers behind. Then you have to buy tickets again because it’s in their terms (and I believe other airlines terms too) that they cancel remaining legs if one is missed, and there’s nothing you can do about it

The last time we flew Delta, we were underwhelmed. Our flight was delayed several hours and there was nothing exceptional about it when it did finally leave.

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.

We compile tonnes of data for you
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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
