1/10, I have never experienced the amount of delays, my flight was supposed to board at 8:34pm, we didn’t board until 3:35am from RDU. The staff got rude and very disrespectful when you asked what was going on it was like we didn’t board until something wrong or were pestering them for answers. I was 1 question 1 time, they were not communicating with us at all. So when our plane was now 6+ hrs delayed and nothing was being said to us .. yeah I think we have a right to ask a question. Everything took so long and was such a process; I have never experienced this before and I’m a frequent flyer, breeze makes spirit airlines look like a 100/10 airline.
