I am connecting from a CX flight from HKG (CX701) to a TG flight BKK - HKT. The flights have been booked separately on different PNRs. The CX flight arrives in BKK at 17.50. I booked a flexible J ticket BKK - HKT. At the moment I am booked on TG223 at 19.15.

My question is is this long enough to arrive in BKK, clear customs, immigration and check-in in time for the HKT flight? There is one later flight but not until 22.40. Also if my CX flight is late and I miss the 19.15, will I be a no-show and cancelled or would I be able to book myself onto the later flight on arrival in BKK.
