Further Details
The original flight was an hour late arriving from Spain to East Midlands due to "crewing problems" in Spain so the Captain informed us. We were boarded and the plane left the stand approx. 1hour 10 mins behind schedule. We then "parked up and the Captain informed us that he would be returning to the stand as there was a problem with the air con and as this was a safety issue he could not fly until an engineer had inspected the fault. Within half an hour the fault had been repaired and we all cheered the blast of cold air. However, the Captain then informed us that because the flight crew may possibly be "out of hours" because of these delays a replacement crew was being sought. Within 15 mins. the captain announced that a replacement flight crew was not available so the flight was being cancelled.
We were transfered by coach from East Midlands to Luton for overnight accommodation and finally left for Prague the following morning from Luton.
