My friend< I read out your curiosity regading eticket. No problem having eticket in travelling. You need boarding pass from-to. You need to show up your ID/Driver lisence when you reach in the airport afterthat the employee of your airline will give you boarding pass and arrange your baggage and you can collect your baggage in the final destination. I couldnot inderstand what do you feel uneasy on eticket? If you mention your problem on particular, I can tell you on that point. Feel free to explain in detail what's your need.
