More questions about JustFly

Aren't these guys the biggest pieces of shit ever? does justfly work in Brazil? if i were to cancel a flight would i get a refund or be able to change the dates ? I just read comment about your company. IS it true? they complained a lot? I just bought the ticket, so i really worry I am reading a lot of negative reviews. I am nervous to book 5 tickets i was about to buy a ticket with them but it looks like it's a big scam so no no i was about to book with you guys but look like your company sucks!! so hell no I have two round trip tickets in June. I see a lot of negative comments, should I be concerned? Why do you tell people you are going to help and do nothing ...just a bunch of excuses ... I hope we can get a class action suit going on you people! Does justfly book hotel n flight together
