Hi all - new to this, but I'm glad this thread is here to help with our newbie questions! Here's my info, in case anyone wants to chime in. I suspect AA is my best bet, because they dominate my home airport, but I'm happy to learn more.

1. What is most important to you in a frequent flyer program (FFP)?
upgrades, priority services, baggage allowance, good award redemption rates, better award access, lounge access, etc.
>>> Mostly good award redemption rates. Flying is expensive and I like to travel, so saving money on flights is the main priority.

2. How many miles do you usually fly each year? How many flights/sectors?
less than 25000 miles, 50000+ miles and 20-25 flights, etc.
>>> <25000 or 25000-50000, depending on the year.

3. What fare class do you usually buy?
first, business, premium economy, economy
>>> Economy. First/business are nice if I have some extra miles, but getting to my destinations is the most important thing

4. Are you able to choose your airlines and/or class of service? Do you travel for work and/or pleasure?
>>> I travel for work and pleasure. I choose the flights myself for work.

5. Which routes do you fly most often?
transatlantic, domestic USA, intra-Asia, etc.
>>> Transatlantic (to Europe) once or twice a year, and several domestic trips. When I'm in Europe I will fly a lot within the continent.

6. What is your home airport?
>>> PHL.

7. Do you have status in any FFP? What is it? How miles do you have banked in each FFP, if any?
>>> Not yet.

8. What are your preferred airlines, if any?
>>> AA if only because I have a decent number (~70k) accumulated with them, and more on the way from the Plat Select and CitiGold offers, as well as because they have by far more flights from PHL than any other airline.

Thanks!
