Sorry I’m a bit late to this post but I travel a lot for my job and have tried various different ways of dealing with my Lantus dose. When I went to Bangkok I was advised to take my normal dose at the normal UK time and then take half the dose 12 hours later then back to normal dose the next day. When I went to Kuala Lumpur (same sort of part of the world) I took my Lantus at 9pm rather than the middle of the day. This turned out to be a bit of a pain as I kept forgetting at first so I posted a note on the wall at work to remind me. When its just an hour difference in Europe I adjust it in half hour stages both ways. Hope this helps.
