Thank you for the suggestions.

I called the service center a few days ago. Even before I finish telling the agent about my problem, I was told that I was the 10+ person on that particular day complaining about the same problem. She went ahead and asked me to email my documents to the quoted email address. It seems there is something wrong with the website for missing mileage applications.

I assumed all schedule flights operated by EVA Airways are eligible for mileage, since TPE - IAH is newly opened in mid June. Asiana Club refused crediting the mileage citing that route by BR is ineligible.
