When planning a trip, we always pay attention to the cost of travel, that is, air tickets, because in most cases, air tickets and accommodation costs are the main part of travel expenses. For ticket classes, not everything is so simple. On the one hand, promotions are the cheapest, but on the other hand, in the premium class, there are more mileage accumulation, the possibility of changing the date, the ability to refund and most importantly Yes, the number of luggage is also different. In the ticket class, you can carry 1 piece of luggage weighing 24 kg with you, and in the class, you can carry 2 pieces of luggage with you 24 kg each. If you carry a lot of luggage with you, sometimes a higher level ticket will be cheaper, because the excess weight is charged per kilogram, and the additional 21 kilograms can be very expensive.
