You seem to be assuming that each and every aircraft is being flown to full capacity during the whole summer but judging from last year and particularly this year Summer 2015, there is a certain amount of leeway in the programming of the aircraft. This is evident when there is an issue with an aircraft, a replacement is either readily available from the same base or within a short space of time another aircraft is on its way from either LBA or MAN. At times aircraft have been sent to the rescue from the base at ALC. All the foregoing is to help avoid claims under the EU261 ruling. Doubtless this policy has also been reflected in the programming of Summer 2016, so that the relatively minor adjustments and additions of destinations for the Summer 2016 programme can be assimilated by the B733s and the B738s, as they will not be programmed to operate to their full capacities at their bases.
