Check-in is usually the first procedure for a passenger when arriving at an airport, as airline regulations require passengers to check in by certain times prior to the departure of a flight. This duration spans from 15 minutes to 2 hours depending on the destination and airline (with self check in, this can be expanded to 30 days, if checking in by online processes). During this process, the passenger often has the ability to ask for special accommodations such as seating preferences, inquire about flight or destination information, accumulate

Types of check-in
Destination or Point Check-in
If passenger is checked in for only one sector of the flight, then it is called destination or point check-in.
Through Check-in
If a passenger is checked on all the onward flights and has boarding passes for all the connecting flights and bags are also through checked i.e. passenger does not need to recheck him/herself and the baggage again on the transit, then the check-in is known as through check-in.
Passenger identity registration
At the time of check-in, one of the agent's primary duties is to check for valid documents. This includes tickets, passports,
visas
Visa most commonly refers to:
* Visa Inc., a US multinational financial and payment cards company
** Visa Debit card issued by the above company

, letters of consent, and in some cases, passengers' address and contact details to comply with immigration requirements.
Some airlines may ask passengers to present the original credit card used for payment.
Baggage registration
At the time of check-in, the passenger hands over baggage which is checked by the airport security and may be sealed (subject to the security regulations in that country). Anything that is above the weight limit or which is not allowed to be carried by the passenger themselves in the aircraft cabin is usually handed over to the agent at the time of check-in. The baggage allowance, if any, is prescribed by the airline and anything in excess will warrant additional surcharges.
Self-service bag drop
Some airlines have a self-check-in process allowing passengers with bags to check-in at Self Bag Drop machines. Passengers then attach the baggage tag and drop the bag at the baggage drop belt. Passengers without checked luggage can go straight to the lounge (if entitled to lounge access) and check in at the kiosk there using their ePass (a small

device only for its premium customers) or proceed straight to the departure gate. Many airlines use electronic check-in such as ePass, mPass, or similar mobile apps, and these applications serve as the boarding pass.
Seating assignment
Usually at the time of check-in, an option of selecting a specific seat is offered, with passengers asked if they prefer a window or an aisle seat.
Online check-in
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.
This service is generally promoted by the airlines to passengers as being easier and faster because it reduces the time a passenger would normally spend at an airport check-in counter. Some airlines, however, would still require passengers to proceed to a check-in counter at the airport, regardless of preferred check-in method, for document verification (e.g., to travel to countries where a visa is required, or to ensure the credit card used to purchase is genuine and/or matches the identity of the person who made the purchase). If passengers need to continue the check-in process at the airport after performing an online check-in, a special lane is typically offered to them to reduce wait times unless all desks are designated as baggage drop-off points. Furthermore, online check-in for a flight is often available earlier than its in-person counterpart. The process then transfers to passengers' control over their check-in. Airlines may use the system because self-service is frequently more efficient to operate, with a greater ability to cope with surges in passenger numbers. It also lessens activity at the airport, saving airlines money and reducing passenger waiting times.
Ryanair

charges passengers a fee which can amount to 60 Euros for ''not'' using online check-in, except in certain limited circumstances. Furthermore, by the start of 2010, all passengers were required to check in online, therefore abolishing the use of check-in desks. Despite this, passengers are still charged to print their boarding cards out.
Online check-in is increasingly becoming required in other legacy carriers, particularly in Europe as the airport check-in desks are being relegated as baggage drop points only.

was the first to offer online check-in. The system was first offered on a limited basis starting in the second quarter of 1999, and was available to the general public on selected flights the following quarter. Since then, a growing number of airlines have introduced the system.
British Airways were the first airline to deploy online check-in globally having sealed approval from both the CAA (Civil Aviation Authority and FAA (Federal Aviation Authority) for use of the 3-D Barcode technology.
Typically, web-based check-in for airline travel is offered on the airline's website not earlier than 24 hours before a flight's scheduled departure or seven days for Internet Check-In Assistant. However, some airlines allow a longer time, such as

, which opens it 30 days beforehand. Depending on the airline, there can be benefits of better seating or upgrades to first class or business class offered to the first people to check in for a flight. In order to meet this demand, some sites have offered travelers the ability to request an airline check-in prior to the 24-hour window and receive airline boarding passes by email when available from the airline. Some airlines charge for the privilege of early check-in before the 24-hour window opens, thus capitalising on the demand for desirable seats such as those immediately behind a bulkhead or emergency exit row, such as Ryanair, which allow check-in up to 60 days before the flight for passengers who pay for a seat reservation.
Mobile check-in
In the mid-late 2000s, checking in was made possible using a passenger's mobile phone or
PDA. A GPRS or 4G-capable
smartphone
A smartphone is a portable computer device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, whic ...
or an internet-capable
PDA is required in most instances (Finnair allows check-in by text message), and the check-in feature may be accessed by keying in a website on the mobile phone's browser or by downloading a dedicated application. The process is then similar to that which one would expect when checking in using a personal computer.
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 barcode that can be presented to the staff at check-in or scanned at the kiosks to continue the check-in process (i.e., to have boarding passes issued).
One disadvantage of early check-in is that it puts a restriction on a person's agent changing their flight. As the ticket coupon has to be "opened" again prior to any changes being made, this may take some time to arrange.
Premium check-in and lounge access
If the passenger carries a first or business class ticket or presents a certain

membership card (usually the higher-level tiers), or any other arrangements with the carrier, access to the premium check-in area and/or the

Premium check-in areas vary among airlines and airports. The main airport in which an airline hub is located normally offers a more thorough and exclusive premium check-in experience, normally inside a separate check-in lounge. For example,

In-town check-in

In some cities (including Bangkok, Dubai, Sharjah, Hong Kong, Kuala Lumpur, New Delhi, Chennai, Seoul, Vienna and Taipei), certain airlines provide in-town check-in services, allowing passengers to check their luggage at check-in counters located in
railway or subway terminals as much as a day ahead of time.
This service allows passengers to
take a train to the airport without the burden of carrying their luggage to the airport terminal. In Seoul, for example,
