Not had access to my PC today, so a belated thanks to LAX-LHR for the info. on TCX long haul plans for S2017.
Delighted that SFO will be on MAN's departure boards and to see the frequency increases planned for LAX, MIA and JFK.
Interested to read ANT's comments about the TCX Premium Economy product.
In terms of the other carriers, VS I would regard as a proper P/E product while that provided by DL & UA is Economy Plus or some such name. VS definitely best based on my experience with DL ahead of UA.
