Hi

Time to cash out I think! This is what I want to do, there's availability for my dates according to ANA: is it valid?

2 one ways:
LHR - LAX -surface - SFO - PDX (NZ/UA Y)
LAS - SFO - surface - PDX - FRA - LHR (US F LH F/C)

nested so we actually do:

LHR-LAX
Drive to LAS
LAS-SFO
SFO-PDX
PDX-FRA
FRA-LHR

I'm guessing that even if the surface is allowed, that second one isn't going to be permitted as it will be classed as backtracking (even though it is surface to Portland)?

ANy thoughts before I try and book it?
