Hello everyone

I have a USD800 travel credit issued for an international VDB.

Am currently based in London (UK) and am wondering what the process is to use them. I am booking a complex itinerary, and therefore would like to get it reserved before I get to the airport where I can get it ticketed (as I won't have the internet at the airport, so can't see availability etc.)

Can I call reservations and get them to hold the ticket booking for 24 hours? It will be a discount economy ticket.

Thanks
