Thank you

You might want to check the OneWorld Alliance board:

Be aware that L class on different carriers' metal may give you different mileage depending on program. So, while I second Slippahs' comment, you also need to check BIS miles spent on each carrier. Also, depending on your status, the order may vary--you want to get to ruby/sapphire/emerald as quickly as possible to get bonus miles.

Hmm wo is that a "round trip" :)

Seriously though I think you should look more at who services where you live. For example if you are in the US you probably would get better overall service from American as oppossed to say Iberia...

Just my 2 cents
