Booked single DL-issued revenue ticket IAH-DTW-NRT-TPE. 50 minute connection at DTW is tight if IRROPs arises at IAH. In preparation, I am working out re-routes to feed to the DL agent.

Delta.com does not price IAH-SLC-SEA-NRT-TPE as valid itinerary, so I suspect 37 minutes domestic-international connection is below MCT at SEA. Additionally, IAH-SLC departs almost an hour earlier than IAH-DTW, so unless IRROPs arises relatively early, re-booking through SLC would be difficult.

Does DL allow re-book onto SkyTeam carrier for one or more segments? IAH-SLC-SEA-HKG-TPE can work with HKG-TPE booked on CI. Alternatively, IAH-ICN-TPE all on KE. I cannot find any other all-DL routing that departs after the DL IAH-DTW flight.

If anyone can find valid routings, I'd be very interested to hear about it. Thank you for your input as I rarely venture over here!

DL SEA-ICN and DL DTW-ICN arrive too late to connect to last KE ICN-TPE flight. DL LAX-NRT departs too early for IAH-originating flight. MSP-NRT, ATL-NRT depart earlier than the DTW-NRT flight.
