We will be travelling from LGW airport to South East Asia on 13th December on Vietnam Airways, landing on 14th December at Noi Bai .
On 13th January we will be leaving Thailand to get back to LGW, but via Noi Bai again.
Our flights look like this:
LGW to Hanoi, Hanoi to Bangkok, Bangkok to LGW direct ( but via Noi Bai).
I am a little bit confused what sort of VOA do we really need?
Is single entry visa OK, since our last leg flight is BKK-LGW ( but via Hanoi where we will be changing planes)?
Man thanks for any advice.
