Any magic website like this?
 

I want to know how many miles different airlines need for flights from Hong Kong to New York, either business class or first class

I dont want to check on each airline's website, so complicated

just like wheretocredit.com ---- a website where u can find all miles-accumulation information for most of the airlines

Use at your own risk. They may not be up to date and do not cover all frequent flyer programs. Some ffp's/airlines have cash award surcharges.

Have not seen one for earning miles. It more complicated with many variations
