I have a return flight in J on Finnair (BKK-HEL-JFK), but was hoping to not always have departure flights booked for other countries until after I’ve arrived.

How strict are the countries and LCCs over there when it comes to showing proof of onward travel? Are certain countries and/or LCCs known to be more (or very) strict? If I fly into, e.g., Indonesia or Vietnam or Myanmar and they ask for onward travel, will showing them my ~$1,500 BKK-HEL-JFK ticket likely to be good enough?

Thanks very much.
