In July, I bought an AI ticket (C-class) for BKK-HKG. Unfortunately, I missed the flight, but as I quite often fly this route, I thought I would use it next time.

Now, apparently, AI has discontinued this route. What should I do?

I bought the ticket in a travel agency in Bangkok (downtown), and I am not sure I can find that specific agency again.

ARCC/NON END/NON RER/NOT VLD FOR CONVERSION INTO MCO.
