We recommend checking out the company's website for more details on baggage allowances, since luggage policies vary depending on the airline you are traveling with.
Generally, at least one piece of hand luggage is allowed on-board free of charge. Some airlines, however, admit one extra smaller piece such as a computer case or a handbag and they will have to be stowed underneath the seat.
In regards to checked-in luggage, different fees apply according to the weight and the number of pieces. Still, one pushchair, foldable baby stroller or infant car seat can be checked in free of charge for each small child.
If you want to travel with larger luggage, please make sure to directly contact the airline beforehand to arrange any necessary details.
