What airports allow connection flights and overnight stays for travelers heading to Thailand from Vancouver?

Traveling from Vancouver to Thailand has become challenging due to restrictions on transit flights, particularly through Taiwan, which has closed its borders. Passengers can consider alternatives through airports in Korea or Hong Kong, which offer viable connection options. Some travelers noted the possibility of long layovers, but suggested that airports might allow staying within the transit area without needing hotel accommodations. Useful routes include different combinations like Korean Air via Seoul or Cathay Pacific via Hong Kong. Additionally, travelers must adhere to COVID-19 testing requirements prior to departure, which might also influence flight choices.
