Also the BKK plane leaves at 0900 and doesn't get back until 2045. Its being used 12 hours just to do a turn.

Same with SGN. Its gone from 2215 to 0935.

Both planes are flying at the same time.

Plus the flight to Hong Kong is 15 hours there and 13 back. That's 28 hours plus ground time. So even before the plane can land back in LAX you already have another plane flying to HKG.

With the way this is set up there will be a total of 6 planes to service this route. 2 flying to HKG, 2 doing the turns, and 2 flying back.

Its not possible any other way.
do you think perhaps the plane coming from LAX will go to SGN at night and the plane coming from LAX in the morning will go to BKK? I am not saying that the specific plane will be used to do both, but there will not be 2 planes dedicated to running both these routes. It was specifically designed to be able to use 1 plane, as I understand it, they company would not be doing the service if 2 planes were required.

What we really need is a nonstop SFO-BKK (Thai Airways did it for a short while back in the day, IIRC). And 1K members get free limo transport to Soi Cowboy 🤠

That still takes 6 planes. You have a plane going from LAX-HKG. Then it goes to BKK and sits for 7 hours and then flies back. Then it flies back to LAX.

Another plane has to do the same thing and go through SGN.

That whole event can't be done with 4 planes because 15 + 3 +3 +13 is 34 hours, plus its on the ground 4 times (one of which is 7 hours and the other 2 times its over 2 hours.

So if you took snapshots of 787s Flying LAX-HKG-BKK-HKG-LAX and LAX-HKG-BKK-HKG-LAX at different times you'd see between 4 and 6 planes.

Also your "1 plane theory" does work with the published schedule. you have a plane that doesn't land until 0935 but its taking off at 0900. That's 2 planes. Plus 4 to fly 2 daily HKGs back and forth. 6 total.

Worstpilotever is correct in that it will only require one additional 787 to add BKK and SGN. Turbosina is also correct in that it’s not the same one plane that will be used to fly HKG-BKK and HKG-SGN everyday.

You need slightly more than 1 plane to operate HKG-BKK and HKG-SGN. That will come from efficiency gained for the long haul flights coming into HKK. What worstpilotever was trying to say is that only one of the new 787 deliveries will be used to add BKK and SGN service. The rest will come from more efficient use of the long haul planes flying into HKG.

I tried to find a correct argument in friendlypilot’s post but I could not find one.

AC#1 departs LAX for HKG at 2255, arriving at 0700. departs to BKK at 0900. Returns from BKK at 2045. departs for LAX at 2245.

AC#2 departs LAX for HKG at 1110, arriving at 1915. departs to SGN at 2115. (RON SGN). Retuns from SGN at 0935. departs for LAX at 1125.

If united airlines had only 5 787s, they could operate this schedule. If they had only 4, they could not. If they had 6, they would have 1 left over.

for FriendlyPilot and anyone else confused by network planning, when in doubt track the aircraft flow:

It currently takes ONE 787-9 THREE DAYS to do the entire routing:
LAX(am)-HKG-LAX(pm)-HKG-LAX(am). [69:15 hrs for this routing, current/old schedule] (3 days)

That's THREE planes to fly this currently on a daily basis.

New routings:
LAX(am)-HKG-SGN-HKG-LAX(am) [44:55 hrs for this routing, new sched] (or 2 days!) AND ALSO
LAX(pm)-HKG-BKK-HKG-LAX(pm) [44:30 hrs for this routing, new sched] (2 days as well)

That's FOUR planes to fly two routings that take two days each.

A increase of only one 787-9 to complete the circuit(s).

Part of the utilization time benefit is also reduced 787-9 sit in LAX.
(6:05 on the current pm LAX "turn" to a max of 3:30 on the new schedule)

Of course, the SFO flights to/from HKG are irrelevant, since they utilize 777s timed for the connections.

"Slightly more than one plane" is two planes.

The first snapshot is out.

334 Total awarded but there were only 182 available bids.

152 Backfills. Even 737 CA and 320 CA were backfilled in 6 different categories even though only GUM 737 was posted, although not in large numbers.

I guess we aren't "overstaffed everywhere".
