Avianca made us wait 3hrs on the plane with no AC, people were having panic attacks and crying, staff did not keep us constantly informed. They told us we was going to be ready in 12mins then one hour later nobody still didnt inform us what was going on. I felt so bad for the people who had panic attacks. The staff did not even offer us water. They finally canceled the flight rescheduled the flight for 730am. The original flight was scheduled to leave at a minutes after 9ish I'm just getting to my hotel at 230am due to mass confusion and alot of horrible organization.
