I'm surprised a 737 can fly for 7 hours without refueling. What ****ty budget
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.

The plane is a derivative of the BBJ, the biz jet version of the 737,
which has a range of 6200 nm with 8 passengers. Sounds like this
airline is more likely to fly the BBJ.
