I was flying from ESSA to EGLL and i was asked to hold at LAM. I followed hold and descended to flight levels as per ATC instructions. Initially i was told to hold for approximately 18 minutes but i never received any instruction to leave hold even after 25 minutes. Even ATC chatter with AI also stopped in the middle of hold. When i reached critical fuel levels, i had to leave hold and follow approach and landing without ATC.
Is it possible to request exit hold to ATC?
