Just received notification of a change of plane for our first trip of the year next Sat - easyJet from Gatwick
Originally an A320 with 31 rows of seats, that's been changed to an A319 with 26 rows.
5 rows x 6 seats = 30 fewer passengers
Usually this close to a departure in May (and in Sep/Oct) I'd expect to find cheap seats rather than a change of plane
