As a Vayama/KE/TG customer who had tickets cancelled and reinstated, I can only assume that Vayama is watching this thread and will start proactively checking reissued tickets to be sure they are complete.
The alternative, in my mind, is that I get stuck in RGN, buy tickets at the counter to BKK at least, and potentially further if KE gives me a problem in BKK for having missed my first leg.
Then, I get home and look to Vayama for reimbursement. I'm pretty sure the DOT and small claims courts will make me whole.
Granted, my tickets are many months from now, so I have the luxury of waiting. But I think it's time for Vayama to tell us if they're working on this. It's certainly more efficient for them to say so here than for each of us to email them.
