You're right and it's the delay arriving at CPT that matters. On reading the OP my first instinct was that delay compensation was due, however you do mention " the congestion at the airport and lack of permission to take off." That indicates it may have been ATC that caused the delay which means potentially outwith QRs control and no compensation under EU261. No harm in trying though.
