With many airlines only giving 15kgs as standard now lot of people are using holdalls which are light.
Argos have many sizes in various designs.
We bought 2 Areolite cases last year and when full on this years holiday have only weighed 13kg and 14 kgs.
The are easy to manoeuvre as they have 4 wheels.

Although I've got a couple of sets of suitcases I don't really find them that useful. The middle size is often not big enough and the smallest is just too big for companies such as Ryanair. Weight is the most important thing to consider. Several years ago I bought a large soft wheeled expandable case from Tesco at the ridiculous price of just over £13. It is still going strong after over a dozen trips and will be used again in a couple of weeks. I recently bought a small wheeled Borderline case with 2 front pockets specifically for Ryanair and that cost £17.

i got a couple of guaranteed to fit Ryanair wheely [but flexible] cabin bags which also fall well inside the squeezy jet limits, they have been a godsend and i picked them up nearly 2 yrs ago for about a fiver each [with a £20 fuel purchase] from a local garage

thank you!! I still havent bought my case yet haven't found one i really like as yet.

any one know were on forum I can download and print of suitcase tags? I got them of here a few yrs ago, but cnt find were on site thanks

Bear in mind that your case for Ryanair hand luggage needs to have an outside pocket to take your (small) handbag with tickets, passport, etc. as you can only have one piece of hand luggage.

bought a hand luggage from amazon
