No I was commenting on christep's unedited original note (one extra Euro seg when he meant one extra NA seg) - now corrected. DXB is fine for miles/TPs.

If I understand your post correctly, you're interested in maximizing BAEC tier points, with the destinations somewhat secondary? (Except for free beds in DFW and MCO?)

If that's the case you ought to exchange some of the shorthaul (under 2000 mi) legs in N. America and go for >2000 mile ones. Also, note that JFK-LAX Iis operated with 3-clsss aircraft where your DONE3 will book into D instead of A (which provides 180 TP instead of 120.) Other transcons (SEA, some SFOs, SAN) are operated with 2-class planes. If you're not desparate to fly only between JFK and LAX then that's a better yield on TPs. (LAX-MIA is also a good tier point transcon.)

For 2000+ mile (120 TP) J/D segments that aren't transcons (thus permitted more than once) look at ORD-SJU and DFW-SJU. If it's just a mileage run then something like (HKG)-JFK-SFO-ORD-SJU-DFW-SJU-ORD-(LHR) would earn you 720 TP v. 360 TP in your original itinerary. Or you could use the LAX-MCO on a 2-class 757 for your one transcon and still visit Mickey.
