The crew sent to board the ill fated jumbo jet is in the "Remora", which is clearly a modified F-117A Stealth Fighter, but retaining the same dimensions. It would be physcially impossible to fit that many people and such a spacious cargo hold into a plane that size with the engines. In fact, with the additional weight, the engines would have to be even bigger for it to operate.
Oceanic Airlines seems to be an airline name often used in action movies and TV series involving ill-fated airplanes. Lost and Turbulence (which reused external shots from this film) both feature Oceanic planes that meet some kind of disaster.
