Missing Airport - Kaunas (KUN) Lithuania

[mmandorino]

I am trying to submit an expense for a flight, but the system requires me to select both the departure and arrival airports from a drop-down list.

The flight departs from Kaunas, Lithuania. The airport code is KUN. However, I cannot find Kaunas Airport / KUN in the available list.

Could you please advise me on how to proceed or whether the airport can be added to the list?

Thank you in advance for your support.
