I bought a ticket on Ctrip.com and picked up my luggage at Kansai Airport in Osaka, Japan in May to transfer to an international flight back home. The 2-hour transfer time should be tight. Normally, international flight transfers require at least 3 hours to ensure enough time to collect luggage, pass security, go to the boarding gate, and board the plane. However, the specific situation needs to be determined based on the actual operation of the airport and the connection time between flights. It is recommended that you check flight information in advance, confirm the specific transfer time, and allow a certain amount of extra time to deal with possible delays or other unexpected situations.
