Hi. Managed to bag an Upper Class upgrade to Miami in December. However it has been a week since the booking and I've still not received my e-ticket. I'm told there is a backlog and it's in the queue. Is there anyone else facing a similar delay in receiving their e-tickets?
Welcome to V-Flyer

Yes this is quite common. Ticketing is done manually by VS staff and word is that there is only a very small team doing it. Typically they're done in order of soonest flight so if yours isn't until December it could be a bit of a wait.
It's quite frustrating, especially if you've been waiting a while. It'll arrive eventually though!
