Flying by low-cost airlines has become very popular nowadays. Of course, this type of travelling Like any other has its cons and pros. Here are some tips for those who want to travel on budget. Fees, luggage allowance and other details of the flight can vary greatly from one airline to another. Some of them charge you for booking online while others add fees for buying a ticket at the airport. Fees can be different within the same airline depending on a destination. So, you'd better find out about all the fee and policies before booking a flight. And don't forget to read the fine print and confirmation email after your booking. 18 Low-cost airlines try to save as much as possible, that's why they often fly to smaller, lesser known airports, which are situated outside the city centre. Sometimes, getting to the city from the airport could be more expensive than booking a flight at a higher price but landing in the main city's airport. So before booking, know where you will land and figure out how you will get to the place you finally need. 19 All the airlines offer such side services as choosing a seat, which means you'll pay extra money if you need more space for your long legs or if you want to sit next to the person you're flying with. To make this happen for free, don't hurry to check in for the flight. The system works so that it picks worse seats first, keeping the best ones for those who choose the pick a seat option. But eventually those who check in three or four hours before the flight can get the best seats for free. 20 Before you press the book button make absolutely sure your name, your birth date, the flight date and other information you fill in are correct. Even one wrong letter may lead to spending a lot of money on paying a huge changing fee and paying an additional fee for using the call centre. This is especially tricky if you're booking with your phone as autocorrect can root against you. 21 When it comes to the luggage allowance, all budget airlines stop being your friends. Don't forget to check the particular airline's website for up-to-date luggage requirements, prepare yourself for not taking some essentials like a Swiss knife or a bottle of your favourite shampoo with you and certainly check how heavy your backpack is ahead of time. If it's over the limit and you still need everything you've packed, then why don't you try to put on all the heavy clothes and fill your pockets with the heaviest items.
