A special round trip ticket is in fact, a combination of 2 tickets. We sometimes have an agreement with airlines at a special low price. This combined with another flight we can get you a cheaper airfare. We mark this as "Special round trip" and issue two or more tickets for your flight. In some cases, the baggage allowance may vary so please make sure you have all the information before going to the airport, you can get detailed information by consulting your tickets online or contacting us.
