An indirect flight: If there is no direct flight on your desired route and you have to change planes in order to reach your destination, you should take into consideration three very important "details".
The first one is that you should buy your flight tickets separately, as if there were two different journeys. It may therefore happen that the sum you must pay for the tickets of your indirect flight, especially if you buy them shortly before the flight date, be almost equal to the price you would pay for a direct flight with a regular line. Check and compare prices well before buying!
Moreover, when arriving at the airport where need to change flights, you must collect your luggage yourself - as if your journey were over. Afterwards, you need to leave the airport security area, check-in for the second flight and go through the security check once again, before you board the second plane. Be extremely careful, this could sometimes take more than 3 hours!
Last but not least, if your first flight is late, the next one will not wait for you, even if it is operated by the same airline. That is due to the low cost companies' policy stating that flights are independent from one another. They are not responsible for your losing the onward flights, no matter what.
