All of you are correct. 1) UAs heavy maintenance (777, 747) is done at the MOC in San Francisco. A lot of aircraft that go in for B and C checks go to San Francisco. I am not certain if they do D checks at SFO
anymore, but I do know that all wide body aircraft are rotated through San Francisco. Usually this is put into the mission schedule of the aircraft.
In addition, because the aircraft are rotated into San Francisco, in order to make the aircraft rotation work properly, there may be an occasion that for a period of time, the aircraft is positioned for its overseas missions at SFO
. This entails operating the aircraft between the two airports.
While you may think this is a little nutty, it actually is quite cost efficient. If the aircraft can fulfill its complete mission schedule without a delay or cancellation, then there is NO ferrying of aircraft from anywhere in UAs system to SFO
for heavy maintenance. Even though the flights operate as live flights and have light loads, they actually reduce the cost of the repositioning by carrying it live. In the case of AM
flights to SFO
, the flights can be quite full as they do connect to their entire westbound transpac bank that operates in the early PM
The problem UA
faces is now that it has dropped MIA
direct, there is one less route that will be able to accommodate a repositioning flight. You will therefore likely only see the -400 on domestic flights between SFO
. As such, you will probably see the -400 more dedicated to specific flight times on a more regular basis because of the reduction of flying to/from the MOC.
To any of the UA
guys, am I missing anything?
