I think you 'd be better served making social media post(s) and linking to them here so people can upvote/promote/share/like. If they get enough engagement then your are more likely that someone higher up in Pegasus cares and does something.

Good luck with the lost luggage.

That being said, I’m interested in your use case for the BCI? From browsing the available literature, it looks like it may be able to track certain parameters, but to what end?

That truly sucks.

At the same time, you only had one copy of 30 years of research and you put it in checked luggage??

I hope you recover it. I also hope this inspires a backup plan.

I can’t help in any way, but I’m just curious why you decided to transfer it as a luggage and not as a carry on? Why it didn’t have something like an apple tag inside it and why it wasn’t ensured and didn’t have a backup? Did you research Pegasus before the flight to see if it has a good service?

Can it be a chance that customs didn’t allow your luggage to be transferred?
