The transfers drive, from Durres to the Rinas Airport (TIA) in Tirana is around 30-0 minutes. ç
it always depens where your hotel is in the Adriatic seaside of Durres is. I.E if it's Golem area is a bit further, so it needs a bit more time.
Please Note: during summer season, it usually is a heavy traffic entering and getting out of the hotels backstreets, so everybody needs to keep in mind 20-30 minutes earlier than the scheduled transfer to be ready to roll. :)
