I believe the Fueling Manual Requires a Jetbridge at each and every refueling operation. Since the GPM incorporates the Fueling Manual; the more restrictive standard becomes the rule.
Then explain how AA acft can divert to ABI, GGG, MAF, etc, and get fueled. Nevermind the usual 10+ that OKC, TUL, SAT, and AUS get during a full blown wx session. You saying they all go to a gate to get refueled?
