We had an issue with our e boarding pass and it did not work. No one was willing to help. We missed our flight and had to rebook 7 hours later for 3 times what we paid and we have yet to be given compensation

Our trip was to plan my brother's funeral. At the last minute I needed to cancel the trip as we needed to wait for death certificates and could not go to Florida until we have these to present to everyone.. They never answered the phone and when I cancelled the flights on Monday, they charged a cancellation fee on top of not returning any of the cost of the flights. Poor customer service in my opinion.

Unfriendly staff, the pilot never announced anything during the entire flight including we’re at altitude, what the weather was like at the destination how much time is left if we were ahead or behind schedule etc. Very funny gay gene flight crew.

wifi was out for the whole flight despite being an prominently advertised feature. Crew was in training and rather awkward, not able to find items like requested drinks etc. Plane had alert "ding"s going every few moments for the first 40 minutes of boarding and flight.
