My flight to Hanoi with Trip.com booking and Vietravel Airline has been changed from evening time to 00:30am in the morning, which I have successfully accepted and arrived at Da Nang Airport way ahead of time! At the airport, there were NO flight information, NO airline representative at the counter and NO information about CANCELLATION!!! After a few hours of waiting for my flight check-in process, I’ve got kicked out of an airport as well as all other passengers because an airport is closing-security guy said! He also said that all flights have been cancelled. I had ZERO email notifications from Trip.com, ZERO messages and ZERO phone calls! Instead, in my Trip.com app the flight showed scheduled on time! NEVER book ANYTHING with Trip.com because they do NOT communicate with airlines!!! How come you, as the travel agency ,don’t know that the flight has been cancelled???!!!HOW???!!!I have no complaints to operators who answered my call-this is not their fault that Trip.com has the worst communication management!!!
