(1) What is your home airport?
LHR (Other london airports are a bit more of a hassle, but still doable)
(2) What types of fares do you usually buy ?
Cheapest. I only pay more when it makes sense for status.
(3) How many miles do you usually fly each year?
I estimate 30 returns in europe (but 25 have to credited to BA at the moment to renew silver every year, and I assume there will be a few short haul flights that are more convenient on *A)
And add to that 3-4 long haul return flights (30-40k actual miles)
(4) Do you have any kind of status at present? What is it?
Will qualify for BA Silver this year (status match to UA would be available, then, at least for a first year)
(5) What is most important to you in a FFP?
In order of importance:
- Priority check-in/security/immigration/boarding (Less time standing up, more time in the lounge)
- Lounge access (But I can also get that with priority pass, so lounge quality / availability also matters)
- Better mileage accrual (I wouldn't mind getting closer to my redemption quicker, but this doesn't matter as much as the rest)
(6) Which routes do you fly most often (US Domestic, Transpacific etc)
- Anywhere in Europe, but in Switzerland more often than other countries.
- Long haul: in order of frequency: YUL > TYO > LAS > Others.
(7) Preferred Airlines
I don't fly Swiss anymore, now that they are building midget-size seats into Economy. I'm 6'5, so I'll fly any airline with legroom.
(8) Do you travel for work or pleasure? (Can you chooose your airlines, class of service?)
Leisure only.

I plan on flying 2-3 long-haul segments per year on Star Alliance as it seems cheaper than OneWorld for the routes I want to do (London to Montral / Tokyo / Las Vegas)

Besides, crediting the same routes to BA's loyalty programme won't make any noticeable change to my status or lifetime tier points.

Am I right in thinking that I'd get 50-100% of the actual flight length in qualifying miles? If so, I'd probably credit those to Asiana, as progressing towards lifetime status sounds nice to me. Any other program that I should consider in that case?
