I'm another potential AC refugee. I decided against switching last year but I'm reconsidering it again now.

(1) What is your home airport?
(2) How many miles do you usually fly each year & in what class?
(4) Can you choose your airlines and/or, class of service?. Do you travel for work and/or pleasure?
(5) Which routes do you fly most often

I fly about 30-40k miles from DUB to NYC, (work) SFO, (work) and YUL (vacation) each year.

I'm pondering a vacation trip to AUS sometime in the next year though which might be instead of YUL...

(3) What types of fares do you usually buy ?

On AC I was paying for M fares which are about as expensive as WTP+ or equivalent. For my personal travel I book the cheapest fares usually.

(6) Do you have FFP status of any kind of OW or other airline at present? What is it?

I just lost AC*G

(7) What is most important to you in a FFP?

Top priority is totally upgrades. After that lounges (that have showers after red-eyes). Don't really care about the rest.

What I worked out previously was that on BA if I could maintain BA Silver (which I'm not really clear on with the new rules) I could buy WTP+ on all my business flights and upgrade to CW with the miles I earn as fast as I earn them. My personal travel would be in the back of the bus.

What I don't know is how any of the other OW programs stack up. Does AA have any similar benefits? AA flies direct to DUB so it would be tempting to fly them sometimes, at least for the daytime flight.

If I do manage to put together a vacation to AUS obviously BA, CX, and QF are all tempting. Do any of them have any way to get into premium economy with the miles I earn on my business travel?

(8) Preferred Airlines

AFAIK the OW routes to DUB are either AA through ORD or BA through LHR. Are there other options I'm not thinking of?
