i found good deals in ORBITZ.com for Nepal but i don't know how to get hard copy of tickets or boarding passes. has anybody used these sites for out of state travels? if yes, then are they good enough to give a shot? are they reliable? suggestions appreciated.

thanks. 

For most of the major carriers (even for international flights) the tickets are electronic.
If the reservation has multiple carriers (except those carriers who have code share agreements), or airports (country/Immigration) that don't/cant accept electronic tickets, and few other exceptions, you will most likely have an electronic tickets. Commonly called e-tickets.

I am pretty positive your reservation will have a Paper ticket.
I am assuming you are trying to reserve from within the 48 continuous states in the US.
You can expect to receive your tickets within 2-3 business days, once the airline issues you a ticket number.
Orbitz will also charge a separate paper processing fee, besides their service fee. The price of the ticket is directly charged to you card by the airline that own the reservation (the one which issues the ticket number)

People use Orbitz very often for international travel. I havnt come across any Reservation going to Nepal personally, but I shouldn't think it would be any different.

If you found a good deal on Orbitz, I would recommend you to go ahead with it. They have superior customer service *wink* *wink*

I apologize if my reply was ambiguous, and do take it with a grain of salt. But if you have any specific question, feel free to ask. Their website is also  a great source of information.
Also if you dont mind, can you tell me what route you picked, the departure times and connection and the price before and after tax. If you dont want to,  its absolutely fine with me.

"For the hard copy of ticket, I think you can print eticket right away after u paid for ur ticket, so just print it out and it will work"

Well kind of :D

e-ticket/electronic ticket are what they sound like. Its all electronic, there isnt really an actual ticket you print. What you are printing is a receipt saying that you have an e-ticket with the airline.

if you have a e-ticket for travel within US, you can just walk to the airport with Only a government issued ID and are able to board the plane. The airline has your e-ticket on their system.
Many airline even let you check in online 24 hours prior to departure, some even let you print your boarding pass. With some, you actually have to book the reservation directly from them to check-in on their website.

There are of course many exceptions.
AirTran technically do not issue e-tickets. Within the industry, they ticket is termed "ticket-less". Some say they do this to cut cost, some say its just plain stupid and complicates the booking process in the backend.


In anycase, most of this information might be useless to know.
But please do take it with a grain of salt, I have a tendency to be ill informed, frequently.
