I'm in the middle of a true nightmare with flight tickets I bought via Trip.com.
If you are planing to buy flight tickets from them (a very bad idea), you have to consider this:
1. Trip.com's online booking system is limiting passenger's name to 25 characters max. If your 3 names in summary are longer than that, your middle name will be truncated on the ticket.
2. They don't issue separate tickets for each passenger, we are a couple and we got a single ticket for both of us.
So what happened is that I found information that the airline will not allow us on board with incomplete middle name (only my wife's name was truncated, mine was OK). I contacted the airline and they confirmed that they will not let my wife on board.
What's more interesting is that the airline not only refused to change the name for free, but also required double payment for name amendment for 2 persons, not 1, because it's a double ticket, not 2 separate tickets.
I tried to resolve the case by contacting Trip.com's support probably 50 times, via emails and online chat, and not only they didn't do anything (other than the standard "we are very sorry"), but also it seems they totally failed to understand what the problem is. Finally I informed them that I'm planing to take a legal action against them and a member of their support team called me on the phone, saying "But when we did your reservation it was successful"
Unfortunately it seems we will not be able to use the tickets we paid for:(
So please be very careful if you decide to deal with them. YOU HAVE BEEN WARNED!
