Am back!
As usual I panicked for nothing it was a doddle. I got loads of stuff in the backpack and it still only weighed 8.75.
It's the first time I've travelled with hand luggage only and I was really impressed. We got to East Midland airport and went straight through security (no waiting in line to check in). It did feel a little strange as I felt I should go and tell someone I was there
On landing in Fuerteventura were were off the plane and out of the airport in minutes. Same obviously on the return. I'm actually fed up that I've already paid for hold luggage for our June/July holiday but that is for 2 weeks and there isn't a washing machine as it's hotel based, so I may have.......panicked
