Yes, horrible communication. And customer service is only available by text. Which is not instant so be prepared to be heavily frustrated when you have questions regarding your flight leaving on the same day. They do get back to you a day later though.

Their attendants, plane (when it's functional), and app is very good otherwise. It was very easy to even cancel if we wanted to rebuy cheaper tickets, but thankfully we didn't because now I'm trying to file a claim for my expenses with my credit card for food and transportation due to the flight cancellation/delay.
