Seville air traffic clearance delays flight for more than an hour

There was a delay in my flight to to London. Reason for the delay was strange for me.

In order to fly the plane from Gibraltar to London, Gib Air need to receive the clearance from air traffic controller from Sevellie, Spain.

There was another flight from EasyJet to London. However Gib Air did not receive the clearance from Sevellie, ATC to take off. There were ready to give the clearance directly to the Captain in the flight, but not to Gib Air. This delayed the flight more than an hour.

Captains from both the flights went to the control room and sorted.

I dont know who's fault is that or if my understanding of the situation is 100% correct. However passengers on a crowded plane sitting there for more than an hour waiting to take off.

I wanted to to match England Vs Germany match in London. Looks like I haven't missed much?
