Puzzle 1 2022-2023

Oh no! The treasurer of Asset | Econometrics, Matthijs Kroesen, has been kidnapped and we need your help. The unknown kidnappers are holding him for ransom. We have intercepted a message that seems to be encoded. We need your help! Please help us decode the message to find out who kidnapped him and where he is held captive.

We already know that they are located near an airport, because our correspondent heard an airplane taking off during the phone call with the kidnappers. To help you we have given you the last letter he wrote before his disappearance. 

Dear Asset,

I am running a bit late and cannot make it to the meeting.
Best regards,

The treasurer
