Always worth checking luggage and baggage allowances before you travel
Baggage allowances can be complicated, varying according to routes and class of seat and taking into account the number, weight and dimensions of bags, free allowances, and ever-changing aviation rules. In general, excess baggage and special items can be carried for an additional fee.
For all airlines flying into and out of the UK, a recent safety requirement has been introduced restricting the weight of each single item of luggage to 32kg. This is not your full baggage allowance, rather a measure to reduce strains and injuries among baggage handling staff.
