Just found out from RobK (on Airliners.net) why Boeing 737NG delivery flights were stopping at PNI. According to the MAJ NOTAM, it seems that the fuel supply is limited to scheduled flights.
From RobK's post:
- QFULT FUEL AVAILABILITY LIMITED TO SCHEDULED FLIGHTS ONLY. 24 JUL 06:48 2010
UNTIL 29 JUL 23:59 2010. CREATED: 24 JUL 06:49 2010
A0070/09 - QFUAU AVGAS 100/130 OCTANE. WIE UNTIL UFN. CREATED: 17 JUN 22:31 2009"
Delivery flight re-fuleing stopovers have resumed at MAJ with both CDG5536 and GIA8011 scheduled to arrive today from HNL.
