Passengers of Jet2 and EasyJet have been advised to ensure their suitcases adhere to a lesser-known rule that applies to all bags with "wheels and handles."

Each airline has its own restrictions regarding the hand luggage passengers can bring on board and the type of suitcases that can be checked in.

Some airlines enforce strict size limits and holidaymakers found with oversized luggage may face additional charges at the check-in desk or at the airport gate.

EasyJet's standard baggage policy allows all passengers to bring one small under seat bag on board free of charge.

There's no weight limit, but the bag must fit under the seat in front of you and can't exceed 45x36x20cm, such as this Chelsea Overnight Bag from luxury suitcase brand Antler. Read the biggest stories in Wales first by signing up to our daily newsletter here

A secondary rule states that this bag measurement must include any wheels and handles. EasyJet uses baggage sizers at its check-in desks and airport gates and passengers may be asked to place their bag inside to prove that it fits.

One wheelie suitcase that does adhere to these measurements is the Elements Hard Shell Suitcase from Dunelm, which is currently on sale for just £21 in black, Aqua blue, or Olive green.

Dunelm shoppers have rated the suitcase 4.5 stars out of five, calling it "strong and resilient", and "an ideal size for a long weekend away."

If the main body of the bag fits but handles, wheels or straps are poking out and cannot be tucked away, passengers may still be charged.

EasyJet's £48 Airport Bag Fee is applicable to any small hand luggage bag or large hand luggage bag that exceeds that person's paid-for allowance, reports Birmingham Live.

EasyJet has issued a reminder to customers about cabin bag sizes, urging: "If you think your luggage might be bigger than your allowance, please measure it and don't forget to include any handles and wheels, and check it against your allowed size here.

"If it's too big you can add additional baggage in your account before you check in."

They added that passengers with oversized hand luggage would face a fee, saying: "If you're told at the check-in or bag drop desk that your luggage is too big you'll need to pay a £48 fee.

"If our ground crew tell you at the gate that your luggage is too big, you'll have to pay the fee at the gate."

For those looking to upgrade their travel experience, EasyJet offers the opportunity to bring a suitcase up to 56x45x25cm.
