HP no longer serves Hawaii. DL DFW-HNL with a DC10 was cut come months ago. I remember reading a rather long FAQ to frequent fliers regarding the service reduction. I also however had not heard NW cutting LAX service.
All this reduction however, raises the question of whether paper airline TransPacific has a legitimate business plan: fly older DC10s from HNL to SEA, PDX, SFO, LAX, and SAN and couple cheap flights with hotel rooms in a package format. If they can keep their costs very low, well there will always be demand to get to Hawaii.
Lets see TW LAX-HNL/LIH soon!!
