香港航空check-in要睇信用卡嗎?

Not in this case.

Expedia works as a travel agency. Your ticket in fact is a prepaid flight coupon.

Expedia, not the airline, is responsible for any financial issues, such as refund, change, etc.

So as soon as you are cleared by Expedia, you are good to go.

搭過多次細航空公司都未試過CHECK
所以多數都不會CHECK 的
但記得要帶齊登機戈張紙就ok

緊係唔使睇卡，你錢都俾哂，仲有乜好睇，出示護照就可以，印埋e-tkt備用。
