Isn’t London-Texas a little long for a commercial flight on a 737?
PrivatAir flies Dsseldorf - Chicago, Dsseldorf - Newark, Mnich- Newark, Zurich - Newark, and Amsterdam - Houston in A319 and B737 aircraft with extra fuel tanks in the belly and an all business class interior up top.
This has been posted a few times before; please search the forums in the future.
Not to be picky, but Schipol is actually in Amsterdam. 
A duration of 1:50 is not particularly long for a 737. 
(Does that make it a mach 3 flight?)
It says Mach 80 for the speed when you click on the flight page!
My bad, it actually says mach .80 (0.80 without the leading zero)
