OK Sept/Oct flights are now reasonable depending on the date, so I've booked 8 nts (1 in Ibiza, 5 in Formentera and the last back on Ibiza) and the whole lot including decent seat and carry on bag (but no b/fast) cane to £1150. Slightly over my budget of £1k but with one extra night than usual.
So hope the sea's warm and the beer cold!!
Also, looking at a quick break in May and can do the flights there and back for under £100, but with only the underseat case, so I'll strap my heels onto my pet pigeon and point it south. Go that bird and there's extra seed in it when you arrive!!
