well u always stand a chance to buy a ticket on a particular day.i.e prior to the departure it is just a matter of cost.
If your friend is paying for the ticket he can always mention your mail address were the confirmation has to be sent and u will receive it and u can take a print out which is the ticket which u can produce at the counter and u can fly.It is as simple as that.
Be bold and proceed.Вы же русская вот сколько землю вы оккупировали ваши предки чего вы боитесь.
you russians claim that u r smart people then why are u afraid or is it lack of confidence?
