Always check your reservation on www.checkmytrip.com - if you can while you are still on the phone with the agent. On Thursday I changed a miles+cash reservation from SIN to LHR and the flights kept disappearing off the reservation. In this case the agents were in Sheffield and, with one exception, were both courteous and knowledgable. It appeared to be system problems, but not something you want to have to sort out in the rush to clear security and board a plane.

Also, make sure you note down your e-ticket number (also visible on checkmytrip). This is helpful if the reservation completely disappears.
