we are traveling from Chiang Rai (CEI) airport to BKK aiport on last flight on Saturday in June. Flight lands at 8.35 pm and we have international flight at 12.30 am (4 hrs later). Tickets are not bought together so if we are late we will lose our international flight. Just wondering how likely for the flight to be delayed during weekend in June? I tried to search for statistics online for Smile Airlines but coudn't find. Any input would be appreciated.
