Generally said, the open return is possible only in the case of very expensive adult air ticket. In case, when passenger requires certain flexibility of his return we recommend purchasing changeable air ticket with such maximal validity which does not extend his stay in the target destination. The passenger should book the most probable date of his return flight or the date of maximum validity of his air ticket, and then in case of need, he can change the date of return flight for certain fee. The cost of such a "close" air ticket is, even including extra fee for change, usually much lower than the open air ticket. The exception from rule is only junior and student price which often allow an open return without any price increase.
