Hou B.

We needed to edit my wife's name on the reservation to match her passport.
They could not help is the short answer. I called both airlines that we are booked with for international travel, they said the agency had to handle. They agency tried to charge me extra fees but said they could not guarantee it.
And no refunds for the flight because it is through an agency. So I said so we might get stuck in another country? He said you would have to buy another flight.
Mind you I have been dealing with this for 3 hours this morning so far on hold 90% of the time.
I asked where they were located the first time and they lied about their location of the call center which is in the Philippines btw. The hold music is burnt into my soul.
There is no solution but "Good luck" - trying telling that to my wife.
