Bristol-Olbia
The Tuesday flight seems to have been axed, not moved to Wednesday.
The easyJet timetable originally showed this summer-only route operating on Tue, Wed, Thurs and Sat (in fact, the web timetable still does) but the web booking engine is only showing flights available on Wed, Thurs and Sat.
Not a surprise in the current economic circumstances because last summer the flight operated on Tues, Thurs and Sat, so a fourth weekly rotation this summer would probably have been optmistic.
