So there you are, with your suitcases packed, ready to climb aboard an easyJet or Ryanair flight for your summer break.

You have been savvy, knowing in good old-fashioned Jewish tradition that you have got the kitchen sink in your luggage and booked a few extra bags in advance to keep the costs down.

But you have got it wrong.

Most budget airlines allow travellers a standard luggage weight of 15-20kg and, after that, mammoth excess luggage charges apply. Yet getting more bags does not change this — you just split your luggage between more bags. Your weight allowance still remains the same.

The only way you can take heavier luggage is by paying the big bucks — around £15 per additional kilo. So, always double-check your weight allowance before packing your bags.

This way there won’t be any nasty surprises when you get to the airport. And, maybe, dare I say it… leave the kitchen sink behind.
