I got some pictures of an Omni Air B772, N918AX, departing Seattle on July 19, 2012 at around 1700 PDT. Is Omni Air normal at SEA? How often do they come?
Not new; irregular military charters. The 777 isn’t new either - it’s a 1997 model previously flown by United and Air India.
This question is simply answered by itself, Omni does tones of charters for military mostly from SEA- (some where in Japan) and other air force bases. 777 & 767’s are regularly used. 8)
