Easyjet have just released Autumn 2018 seats. Great. Went to book to find there is premium for travelling on your own. I was quoted £49 to Corfu and told three left at this price. Out of curiosity I asked for 4 seats as this should show me what the next price band will be. There fare went down to £34 each. Not a fluke as I tested some other routes too. Never spotted this before. Do cinemas do this too?
