All credit goes to the original authoer: Keldis who has given permission for anyone to transfer this to the Skyrim SE.

UPDATE: Make sure the ESP is towards the end of your mod list.

Ports over the Real-Time Dragon Fast travel to Skyrim: Special edition.

Dragons under the Bend will shout will now fly to a destination you pick on the map in real time rather than going to a loading screen.

I am in no way an expert in modding for Skyrim, I merely transferred the original mod to the Special edition for my own use but thought I'd share it. I have tested it and dragons are now flying in real-time to destinations.

I have fixed the Odahiviing call dragon shout, while not perfect you can now call him as normal then use CALL DRAGON SHOUT 1 to get him under your control. Download Dragonmount Real-time Odahviing command fixed for this version. Credit to Skyward95 for providing the fix.
