Hi all, one question about my upcoming BOM international-international transfer. Two flights are on different PNR/ticket number, but both in T2, layover is 3h05m, no check-in baggage.

Incoming flight: SQ424 SIN-BOM in F class, ETA BOM 22:10 on 14th FEB

Onward flight: AI338 BOM-BKK in J class, ETD BOM 01:15 on 15th FEB

Air India wesite mentioned there is a transfer desk on level 2 open for travellers 24/7. My question is – if I online check-in my AI flight, will Air India transfer desk support to get boarding pass and clear immigration/security for me? Or I need to apply VISA for this transfer?

Many thanks.
