Airborne
From Wikipedia....
The 737-900ER, which was called the 737-900X prior to launch, is the newest addition and the largest variant of the Boeing 737 line and was introduced to meet the range and passenger capacity of the discontinued 757-200.
An additional pair of exit doors and a flat rear pressure bulkhead increase seating capacity to 180 passengers in a 2-class configuration or 215 passengers in a single-class layout.
If a 757 can cross the pond, why cant this aircraft?
Ignoring wikipedia, and looking at Boeing website here
Boeing: Commercial Airplanes - 737 - Range Charts
gives you the definitive answer.
