I am transiting through AMS on an unprotected connection as I booked an award flight. Arriving on SQ324 at 7:15am and departing on BA8496. Without delays it's only a 2 hour 45 min connection and SQ says they can't interline for checked baggage. So I will have to go through passport control, get my baggage at the carousel, drop my bag at the BA counter, exit through passport control again and then if all aligns boards my flight. I will have wifi on the SQ flight so worst case I could change my BA ticket to a later flight in the day. How doable is this?
