On one of my other threads it was me that was asking for cheap flights to Murcia. But I have done all the fingerwork for you.
So, if you especially have kids like me and can only fly in the school holidays or even without any kids. I looked for flights with everyone and at first easyjet lgw to murcia it was £6011.+ baggage+speedy boarding.
So I decided to go to Alicante with them and for 2 adults and a child I got it for £350+£30 baggage+speedy boarding=£440. We chose to have speedy boarding so we don't have to queue up. Hope it helps to anyone who is looking
