Hi guys. It's been really helpful to be in contact with FT until now, and I feel it'll be in the next future. Today I'm buying my ticket, a LONE4, through BA, and I'd love to be given the last advice before I do it. I'll phone and do a money transfer, after that I'm told the tickets will be sent home by mail. The route (it's validated by the agent of BA, but anyway I want to be 100% sure) is as follows:

1: MAD-IST: 1st of 4 (Europe)
2: AMM-LHR: 2nd of 4 (Europe)
3: LHR-DEL: intercontinental
4: DEL-HKG: 1st of 4 (Asia)
5: HKG-SGN: 2nd of 4 (Asia)
6: KUL-HKG: 3rd of 4 (Asia)
7: HKG-SYD: intercontinental
8: SYD-AKL: 1st of 4 (Southwest Pacific)
9: AKL-SCL: intercontinental
10: SCL-LIM: 1st of 4 (South America)
11: LPB-SCL: 2nd of 4 (South America)
13: SCL-EZE: 3th of 4 (South America)
14: EZE-MAD: intercontinental

They say it's OK but I want to assure myself...
Only the dates of the two first flights are closed... the others are opened, I will try to set the date of the AKL-SCL cause I've heard it's a tough one in L-class.

What else... I've joined an AA program, I shall tell it before the purchase, I'm right? I just have to say I want to include my AA number in each of these flights or how should I do it?

I've heard that, since living in Europe and departing from Europe, I can cancel the ticket till the prior day to departure with no problem to get the 100% of my money back... is it sure?

Well, no more questions by now, I'll wait to see if there's any last minute recommendation here before doing the transfer...

Thanks in advance and comment everything, please... I'm no expert and I don't want to do nothing wrong with my money!!!
