Which Side of the Plane Has the Best View of the Seychelles when Landing at Mahe (SEZ) Airport?
The particular flight I am taking is leaving Dubai and landing at Mahe and it is on Emirates, should this make a difference.
If you don't know ahead of time which way the plane will be landing, the port side of the plane has something interesting to see in either direction. The starboard side looks even more interesting if you know that you'll be approaching from the northwest, but if you're approaching from the southeast, you'll just be looking at a lot of ocean.
As was noted in @Peter M's answer, the direction of approach is determined largely by the wind speed at the airport; the fact that it's coming from Dubai is largely irrelevant. All of the airplane in the videos above came either from Dubai or from Abu Dhabi.
That's going to depend on which way the wind blows when you land which is related to the time of year, current storms etc. All you can do is guess the best side and hope that the travel gods answer your wishes.
But in terms of actual data you can make a decision on, you can see from Mahé/Seychelles Airport wind and weather direction that you can make a reasonbly educated guess.
