This is actually a B6 flight number.
It does not sat AA# blah blah ( operated by Jet Blue)

I am Platinum on AA.
It says "on request:"
THree questions

1- can I pick "more room " free of charge -- AA said to call JetBlue , No seat assignments available to select at all.

2._ because this is Non Rev, I assume B6 wont badger me to change FF # to them.
3- Will it be a hassle to get free luggage check in ?
4 - most importantly, if I don't take the trip will AA redeposit the mile without a charge if it is a B6 flight number?

Thanks to all,
