I found this on the BA
forum (credit to Prospero)
Lets begin 2020 with a new topic of "Where in the world am I?"
Inspired and originated by highlander100 back in 2015, the aim here is to truly weed out the travel geeks among us and shower them in all their glory 
The winner will be awarded annually and bestowed with the true knowledge that they are a true Flyertalk KLM Flying Dutchman geek.
Here are the rules and they really are very simple:
1.Take an obscure photo of a KL location / destination you are currently in (or have visited recently). KL codeshare locations are permitted too
2. Post on this thread and add a clue (if you feel it’s required)
The goal is then to be the first person to correctly guess the location.
3. The OP confirms who has the first correct guess
4. The OP updates the list in this post
If the winner has not won before, their name is entered and the post date/time they won is added below. If the winner has won before, the date and time of the post they won is added below their name.
1st: Solevita (post #6)

2nd: Arjen05 (post #17)
(ICN Seoul). Photo#2 (post 17).
3th: TLspace (post #25)
(HUY Humberside). Photo#3 (post 20).
4th: Arjen05 (post #34)
(NWI Norwich). Photo#4 (post 29).
5. To try and keep it further within the remit of the forum, I think double points should be awarded in the event that the OP can get a KL logo into the photo without giving the game away.
- Multiple guesses are allowed.
- Please try and keep it to one live photo at a time.
