Thank you moderator. Your intervention is much appreciated and thanks to FSD for answering my original question.

Current scheduled routes:

so how many A350's will it take to fly all of those routes? I am guessing 5 or 6? I have no idea how aircraft rotations work.

Well assuming all flights are daily, you will need 3 frames for DTW-ICN-ATL-ICN-DTW, 1 for DTW-AMS-DTW, and 6 for NRT, PEK, and PVG. So 10 should be right.

Makes me wonder where the remaining 5 are going to go, I suspect ATL-NRT could and that'd require 2 frames, that still leaves 3 frames, perhaps ATL-AMS ATL-CDG and DTW-CDG?

I wonder if LAX-PVG could be another candidate for the A350 (in addition to ATL-NRT), since it could possibly rotate with DTW-PVG. And with the SYD frame now apparently being positioned via the new CDG/AMS flights, and HND switching to the A333, that would make PVG something of an orphan route at LAX.

If the DTW-AMS flight that is moving to the A350 is the early flight (departs DTW at 1609 and arrives back at 1155), then only 9 frames are needed. Rotation could be DTW-NRT-DTW-PVG-DTW-AMS-DTW-ICN-ATL-ICN-DTW-PEK-DTW. That rotation allows 2+ hours for all turns except for DTW-NRT-DTW with 1 h 50 m at NRT. There's an RON at PVG and one at DTW. I'm sure DL will want a spare or two, but technically only 9 frames would be needed to operate the schedule. If a different DTW-AMS is the one changing to the A350, then it's likely that 10 frames would be needed with an extra frame at DTW overnight.

DTW-NRT/DTW-PEK/DTW-AMS/DTW-ICN/DTW-PVG/ATL-ICN in total should require nine aircraft. There will be another A350-900 delivery sometime in July of next year to finish out 2018. Another route will likely gain an A350-900 destination, most likely a 777 route as the 777 fleet will be undergoing mods to match the A350-900 interior. If Delta were to re-time another route, such as LAX-PVG or ATL-NRT, they could easily switch to the A350-900. I consider LAX-PVG/ATL-NRT/SEA-HKG the most likely routes to go A350-900 by the end of 2019 assuming Delta does not add any new flights. ATL-JNB/ATL-PVG/LAX-SYD are very likely staying as 77L.

DTW-HKG too so it could rotate with SEA.

I'm certain DTW-AMS is being added to increase utilization of the 9 aircraft but the scheduled times will (have) be updated to accommodate it.

When the 10th aircraft is delivered, it'll almost undoubtedly be "based" at DTW -- the current rotation is tight, and becomes tighter with the inclusion of DTW/AMS. There's no operational spare, no slack in the fleet and no other fleet types at DTW that could operate the t-pac routes (the incumbent DTW/AMS partially, but not completely, fills this role). Thus, presumably the 10th aircraft will fill this role. Given the press release (which markets the 359 on select AMS flights), I suspect it'll be tossed on DTW/AMS as well.

I wouldn't look for new 359 routes until 2019.

But this holds true for just about every airline that takes delivery of a new plane of this stature; You can say the same about AA and UA when they started taking delivery of their 777-300ER's. I am sure its a priority for DL to get those 777 mods done so that in the event of a MX issue with a 350, they can at least sub in a plane with Delta Suites.
