Well, dramatically higher prices from Bristol for school holidays - way, way up on last year (about 30% more and that was booking almost as soon as the flights came out) - and now, about eight hours since we booked, flights including luggage are now double what we paid last year and £600 more (£150 each) than when they were released. Expect some return flights in July and August to be around £500 each by later tonight.
This is how any business works and easyJet no different. Charge as much as you can get away with, especially for those who can't go away outside school holidays.
In fact, Thomas Cook flight only from Bristol - with much better flight times, more leg space and more in the way of in flight options - is now cheaper for many dates than easyjet and Thomson not much more.
