I'm looking for an advice from someone who has experience with HEL airport.

I am not a EU citizen. On June 7th (Thursday) afternoon I will have 1 hour and 20 minutes in HEL between my non-Schengen flights: arriving at 15:15 on Finnair from England and departing at 16:35 on Belavia to Belarus.

Do I have enough time to exit through immigration, collect my luggage, re-check it to my Belavia flight, then enter the international area back and be on time for my departure flight?

Oh, and I am oneWorld Sapphire (AA Platinum), maybe there will be expedited security line on my way back inside?
