I am going to take EVA air. I have an United mileage plus account. However, it seems EVA is not a Star Alliance Member. After some search, I found this could be a good solution by using the relationship between EVA- Continental-United:
- Sign up for a Continental OnePass member. http://www.continental.com/web/en-US/apps/account/enroll.aspx
- EVA is one of Continental OnePass partner. Please see http://www.continental.com/CMS/en-US/marketing/custcomm/promotions/Pages/AirlinePartners.aspx
- Use the OnePass to get mileage while flying EVA. The mileage is counted as documented in here. https://www.continental.com/web/en-US/content/onepass/elite/qualify.aspx
- Then convert OnePass mileage to United mileage plus as documented here. Thanks United for merging with Continental. https://secure.unitedmileageplus.com/MP1101OPTM.jsp. This blog also is very useful http://frequentlyflying.com/continental-and-united-airlines-mileage-transfers-plus-elite-status-match-consolidation
I will come back to update my success (or failure) after taking the EVA flight.
