airline was dishing them up for long haul? Let us know so we can avoid it.

It's the 737-700ER, with a range of 5,630 nm. That's enough to get
from London to anywhere in the continental US.

Not I suspect if you include fuel safety margins.

It depends on the wind and the loading. LHR-LAX is 4741 nm, so well within
the nominal range, but if the 737 has max payload and there's the usual
headwind, it may be insufficient.

I suppose, but since the last third of the flight is over southern
Canada and the US, there'd be plenty of places to land and refuel if
need be.
