Experts have warned that Ryanair, easyJet and British Airways may increase charges for oversized bags.

It comes amid rising fuel costs stemming from the Middle East conflict.

As it places pressure on airlines and threatens holidays, the price of baggage and the probability of being charged for overweight items are likely to increase.

Alen Baibekov, CEO of Economy Bookings , said: "There will continue to be large increases in baggage charges going forward.

"There are a number of factors putting downward pressure on airline profitability including increasing fuel costs, higher aircraft maintenance costs, increasing costs at airports and increased price competition among carriers."

He noted that raising baggage prices is likely because this expense is not initially displayed to consumers, who typically hunt for the cheapest flight fares when organising trips.

"Because most consumers primarily compare the cost of air travel based on the "headline" ticket price (i.e., the advertised price) rather than all of the other things that go with the ticket, many airlines have started charging additional items for the true cost of the trip like baggage," Baibekov added.

"Charging for excess baggage is something that airlines can do easily.

"Excess baggage creates tangible costs for airlines.

"It takes up more space and may cause delays when it comes to unloading, checking-in and boarding.

"In addition, if there is excess baggage it may require more labour hours to handle.

"Low-cost carriers are particularly aggressive with excess baggage fees as this is becoming more of a standard in their business model."

Little-known Ryanair rule that bans travellers from flying

Passengers are asked to pay an additional cost to ensure that their journeys are as smooth and as trouble-free as possible.

This includes paying for a larger carry-on bag.

But for those who are budget-conscious - who can blame you - and want to save as much as possible, you'll want to keep an eye out at the gate.

This occurs because Ryanair departure gates do not accept cash, requiring any gate bag charges to be paid via card.

A Ryanair representative stated: "Our bag policy is simple; if it fits in our bag sizer, which is bigger than our agreed dimensions, it gets on free of charge!"
