The flight attendants and staff were all rude. We were trying to make the most of our flight being so delayed, but the attitude from every attendant was very discouraging. Will never fly spirit again.

Flight and Alaska Airlines in general were great! Such kind staff. Kayak on the otherhand was BAD. Awful even! An error on their site forced me to have to find extra lodging for my trip and their representative was dismissive and rude when I tried to let them know about it.

Flights were twice cancelled by United resulting in 2 days delay arriving at destination. Lateness of notification resulted in repeating COVID tests. All flights once i did managed to fly were late by about an hour. No device charges provided in economy class (standard with most airlines).
