Hi, I am currently booked up on a few flights for Vietnam Airlines and I was trying to find where to add my Virgin Atlantic frequent flyer number in manage my booking but could not find where to do so, I would greatly appreciate if anyone could assist me. Additionally, I noticed you can not add your booking to the Vietnam Airlines app you have to keep logging in your details for it to show your reservation is this normal? Most airlines show your up and coming bookings.

Many thanks in advance
