Reply: GLT
(2) How many miles do you usually fly each year & in what class? (<25K, 25k-50k, >50k)
Reply: >50K
(3) What types of fares do you usually buy ? ( First, Business, Economy etc.)
Reply: Economy
(4) Can you choose your airlines and/or, class of service?. Do you travel for work and/or pleasure?
Reply: Can choose airline, but am generally limited to economy, as travel is for work.
(5) Which routes do you fly most often (US Domestic, Transpacific, Kangaroo, in Asia etc)
Reply: Majority of flights will be Transpacific, as well as, throughout Oceania.
(6) Do you have FFP status of any kind of OW or other airline at present? What is it? (AA Executive Platinum, QF Gold, UA 1K, LAN Comodoro, etc)
Reply: N/A
(7) What is most important to you in a FFP? (upgrades on travel, priority services when flying the airline, extra baggage allowance, good award redemption rates, better award access, free - discounted lounge access, etc.)
Reply: Travel upgrades and lounge access
(8) Preferred Airlines
Reply: I assume this would be QA, given the location.

Thanks for any help!
