I sincerely needs d full steps involved in online booking of air ticket, I'm I printing anything and if yes I'm I to visit anywhere with d printed paper?

Sir, you'll do the following:
- Visit the website of the airline company e.g. www.flyaero.com, www.arikair.com, etc
- Select your flight dates and destination and payment option on the website. Aero provides an option for "book on hold" (this means you could book and pay at a designated bank)or have your ATM card ready if you choose the "pay by ATM card option." When you book on flyaero.com, you'll be assigned a code for payment.
- You could decide to check in online or visit the airport of departure to check in. Once you check in, you may need to print your boarding pass for the flight.
- If you can't print it, you will need to write down your code for easy remembrance. When you get to the airport, show them the boarding pass or the code and you'll be allowed to move to the departure lounge.
Hope this helps.

So helpful, I'm very grateful, thank you......

You're welcome sir.
