Not sure why people are acting so surprised that prices have gone up since the news about TC broke.
I imagine thousands, or maybe tens of thousands, of people will have been panic booking alternative holidays today. In the agency I work in it's been non-stop from 9am, people just desperate to go anywhere. As with most things, the more something books up the more the price increases. It got to the point today where there was basically no package holidays available departing this week, save for a few shit ones still kicking about.
It will only get worse before it gets better probably.
