I rang the Silver number only to learn that this open jaws option cannot be MFU'd, since MEX and BOS are in different zones. Damn. I really could not face the idea of MEX-LHR in WTP, so have now bought a roundtrip in WTP from BOS to LHR and MFU'd the outgoing portion. I now need to find a r/t MEX-BOS and am undecided on whether to go for CO or AA. In the former I'll earn full Onepass miles in steerage, and there is always the possibility of an OpUp. On AA it remains to be seen whether the current offer of TPs will continue into June. Any thoughts anyone on which airline I should go for? Neither offers nonstop, so the transit airports are likely to be EWR or IAD for CO and DFW or MIA for AA.
Oh, yes, I have a WTP question too: should I go for 28B or 29A? I am travelling solo and it's a day flight.
