Hijacking this old thread:
Trying to get back to Europe from SIN on a budget in late May. Found a SGN-MUC biz award on VN (through flying blue). If coming in on a separate ticket from SIN (likely on SQ or VN), carry on luggage only, what would be a safe connection time? Do I have to clear immigration?
3 hrs minimum to cope with delays. No need to go landside if you can have your BP either on-line or at a transfer desk.
