Finally, anyone have any experience of upgrading a segment of a MONE to BA WT+ (principally, which class it books into and what miles/tier points acrue), as it is *very* tempting for the LHR-SFO leg for USD300 each (especially the way the £:$ exchange rate is going
) ?[/B]</font>
I have a MLONE currently going ex-Australia. Upgraded the SYD-LHR leg on BA (via SIN) to WT+. It books into T class. I assume you're booking via BA, ... in which case you won't have to explain to them what WT+. I had to explain it to the AA RTW desk and politely tell the lady to go read the starfile. AA office in Sydney wasn't much better - first thing they said when I went to ticket it was "what's this T class?" ... had to explain it to them as well.
It was worth it (A$900 SYD-LHR). Though it's not business class, it's much more comfortable than coach(WT) so the 20 hours or so flying time SYD-LHR wasn't too bad.
On AA, you get 100% miles plus a 10% bonus (versus 25% bonus for business class) - definitely worth it after July 1 when discounted coach tickets on BA will only get you 25% of the miles in the AA program. I assume you'd get 100% plus a bonus in the BA program - no idea about tier credits, though (as tier credits are strictly a BA and QF concept)
