Inbound MAD that night as well. En-route inbound Hold at CLS FL 370 for 15 minutes (never had to Hold en-route in 34 years of airways flying) then cleared onwards to Hold again at Sirgu for 5 minutes.
It was a Sunday night with no MAD ATC working Approach/Final on 127.5 or 127.1, so we just follow the procedural approach and land (fortunately someone was in the TWR, a cleaner maybe?).
Incredible, an EU capital city airport (note lower case) operating like an out-of-hours desert strip
