Airlines and other main providers of the travel industry compete sharply for the favours of passengers and often offer fictitious advantages. The main problem we face with tickets issued by passengers or foreign tour operators is that we are not in control of the whole operation and cannot guarantee its success and will state so in the contract. Since delivery of ground services also depends on correct pickup at airports these might get disrrupted too. Just leave all travel planning to us and relax. No, this wouldn't be convenient in reason of international airfare regulations.
Airlines charge handling fees for the extra work of contacting the beneficiary.
