Online Check-In ... Your time is yours!

What is it??
Online check-in is the process in which passengers confirm their presence on a flight via the Internet and typically print their own boarding passes. Depending on the carrier and the specific flight, passengers may also enter details such as meal options and baggage quantities and select their preferred seating.

Advantages :-	Disadvantages:-
1-Easy and fast as it reduces the time a passenger would normally spend at an airport check-in counter.  2- Online check-in for a flight is often available earlier than its in-person counterpart. 3-  It also lessens activity at the airport, saving airlines money and reducing passenger waiting times.	1-Some airlines, would still require passengers to proceed to a check-in counter at the airport, regardless of preferred check-in method, for document verification. 2- If the printed boarding card is lost it will be a problem for the passenger.

SMS Check-In :-
In the mid-late 2000s, checking in was made possible using a passenger's mobile phone or PDA.  The check-in feature may be accessed by keying in a website on the mobile phone's browser or by downloading a dedicated application. 

At the end of the mobile check-in process, some airlines send a mobile boarding pass to a passenger's mobile device, which can be scanned at the airport during security checks and boarding. However, others send an electronic confirmation with a bar-code that can be presented to the staff at check-in or scanned at the kiosks to continue the check-in process.
