Planning a RTW trip for April. Looks like this.
BOS-YQB-JFK (week layover)JFK-LAX-SYD-OOL-ADL-MEL-SIN-HKG-ICN-HKG-NRT-LHR-CDG-LHR-JFK-BDL
Couple of questions:

Will this itin work?

Doing this in Biz class heard reports of people getting downgraded on OW RTW tix? IS this true?

Booking-BA has a RTW number should I use them or AA?

Any other tips a tricks would be apprciated!

Will finish AA Plat challange next month.:-)

Thanks.
