Questions
For members asking for information, to help people to assist you, can you please provide:
(1) 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: I prefer to use miles for free flights. Lounge access is nice.

(<25000, 25000-50000, >50000 miles - <25, 25-50, >50 flights?)
Reply: No idea how much I'll be flying
(3) What types of fares do you usually buy?

Reply: Private flight selection priority: best connection followed by cheapest flight, any airline. Business: might be business class or priority. Note: this will in most cases be Etihad!
(4) Can you choose your airlines and/or class of service? Do you travel for work and/or pleasure?
Reply: Private: any. Business: most flights will be to Abu Dhabi, thus Etihad.
(5) Which routes and airlines do you fly most often?

Reply: Manchester, possibly Liverpool
(7) Do you have FFP status of any kind in OW or other airline? What is it? Do you have any miles banked in a FFP?
(AA Executive Platinum, QF Gold, UA 1K, LAN Comodoro, etc)
Reply: Qatar Airways Gold, will be downgraded to silver in October
(8) Preferred Airlines? Most common Airlines flown on?
Reply: no preference

Thus: Etihad no connected to Oneworld. Not sure if I'll at least be able to at least maintain Oneworld Ruby. British Airways doesn't seem to give status miles for most economy flights.

Two more economy flights with Qatar Airways planned: to SE Asia return and oneway to UK. Ignore miles, dump in QR even though I won't gain anything from that or are there better options? Someone mentioned AirBerlin as it's connected with Etihad and Oneworld. Would that be an option for award tickets from UK and possibly lounge access?
