Emirates has published a nice fare for travel between Bangkok and Oman via Dubai in First Class but the fun part is you can route via Hong Kong both ways and have 8 segments in First Class and almost 27 hours in the air for an excellent price. You can also have free stopovers in each city.
The sample flights are in August where we can hope and pray some normalcy has returned...
