77O F seats are older ITPE 8 across Business seats like 772A aircraft.
jayunited, I'm still confused. First of all, the quicker the better and extra mod lines would be great.
1.) I don't see why UA can't deadhead the crew from the US through LAX/SFO-HNL-GUM, then after a layover, ferry a single day 73G/8 GUM-XMN-GUM and drop the 772 crew in XMN to pick up the 772 aircraft? There is some slack in the 737 GUM fleet. It looks like the block to block RT GUM-XMN-GUM would be a bit over 8, is that an issue with GUM pilots? I assume a third pilot could be scheduled.
It doesn't matter that UA doesn't fly to China right now, they have to ferry either a 737 or a 772 in any case.
2.) Unless they are incredibly fast (which would be fantastic), N221UA won't be ready in 14 days for N219UA to take it's mod position. Maintenance is usually bundled with the mod work and according to my info, N221UA hasn't had a long maint visit since 2018 in XMN.
For N219UA to enter mod on 3/15/20: 1.) N221UA has a 14 day mod duration, 2.) there's an additional mod line starting 3/15, 3.) the aircraft will wait for an opening, or 4.) the aircraft will use N77012's mod line on 3/15, then slipping 2 more GE772s until N221UA should exit about 4/25.
3.) If N219UA will stay in GUM until 3/15, the ferries you mention makes some sense as the aircraft has to head to GUM in any case. Why not pre-position N219UA by extending the ferry to GUM-XMN-HKG, drop the aircraft and ferry a GUM-HKG-GUM 737 to pick the crew up in HKG.
Your estimated block time for GUM-XMN-GUM is correct but the one thing you are not accounting for is time on the ground at XMN. Also UA is scheduling these XMN and HKG positioning flights with either 3 or in some cases 4 pilots. I'm going to assume that UA in order to appease the pilots feels like it is better to utilize a widebody with lie flat seats than a 737 without lie flat seats because the block time alone not including ground time is a little over 8 hours.
Also N221UA is only at HKG for conversion whereas the schedule is showing N219UA will go in for a C-check and conversion. Perhaps UA will just let N219UA sit on the ground at HKG until a line opens up, I'm not sure if maintenance can start the C-check while N221UA is still in conversio. But for now the maintenance schedule still shows N219UA going to HKG before N221UA is scheduled to leave HKG.
Just when you thought things could not get anymore crazier they just did. N771UA is now being ferried today as UA2757-03 GUM-SFO, maintenance at SFO will perform some work on this frame tonight and it will return to service tomorrow 03/04. The frame that was to temporarily replace N771UA flying routes like GUM-NRT and GUM-HNL was N74007 however after flight UA2700-01 that frame was taken out of service in GUM and now will not return to service until 03/06 where it is scheduled to fly UA200-06 GUM-HNL, then UA396-05 HNL-SFO. As a result of these two frames being out of service N219UA will get quite the work out over the next few days.
N219UA will now fly
