Online check-in: What is it?

Online check-in: What is it?

Online check-in is check-in made via the Internet. An alternative option is a check-in at the airport.


In the case of purchasing the tickets of popular airlines Ryanair, Wizz Air or EasyJet, it's worth using online check-in because check-in at the airport is associated with additional fees.

What is check-in and why should it be made?

Each passenger must have a boarding pass to take a seat on the plane (a ticket itself is not enough to board the plane!). The boarding pass is generated during check-in. There are two possibilities to make it:

  • Online – using the online form, you have to enter the required data, and after generating the boarding pass, you have to print it and take with you to the airport (you will see the details on online check-in in the next part of the article)
  • At the airport – at the check-in desk of an airline or at the self-service check-in desk (machine) – in this case, the boarding pass is printed by the airline employee or by the machine (you can find more information in the article about check-in at the airport).

Each passenger has one boarding pass filled with data, the scope of data is determined by the airline. In addition, the required data may vary depending on the route, which is related to the visa requirement set by the country of arrival. Usually during check-in you must give your name and type, number and series of the transport document (ID card, passport), as well as additional data, such as country and data on the issue and validity of the document. This is important because the compliance of the data on the boarding pass and documents is verified during the security check.

In the case of non-compliance of the mentioned data, the passenger won't be able to pass the security check. Additionally, during the check-in, seats on the plane are allocated – this information is included in the generated boarding pass.

Is it necessary to provide data during check-in? Yes, it's necessary. During making the reservation of airline ticket, you have to provide names and surnames of the passengers, birth date and contact details. The boarding pass includes more detailed information. This results from the applicable safety requirements.

In addition, in the time between the ticket purchase and the flight, the required data may change (for example, the validity of the passport may expire and a new document will be issued with a different series and number). This is why check-in is made just before the departure or in the case of online check-in, it's possible only a few days before the departure. 

Attention! Each passenger should have his own boarding pass filled with the required data and an identity document confirming their compatibility with the actual situation.

Link to online check-in can be found in the email you will receive from eSky

Depending on the purchased tariff, eSky customers can check-in in two ways.

Customers with the Online check-in service

In the case of purchasing an additional service - Online check-in (it's possible when booking an airline ticket on our website), the passenger will receive an e-mail with an electronic ticket and with a link to the check-in form. Thanks to this, the passenger can provide all necessary information for check-in before the airline opens the online check-in (usually takes place 2-4 days before departure). Our consultants will finalize this process when the airline check-in starts. You will receive your boarding pass to print. The boarding pass will be send to the e-mail address indicated in the booking not earlier than 48 hours and not later than 8 hours before the scheduled time of departure.

Customers without the Online check-in service

If the passenger has not purchased the online check-in service, he will receive only an air ticket e-mail and notification of the date of sending the next e-mail - with the check-in form. This e-mail is sent when the airline opens the check-in (for example in the case of Ryanair - 48 hours before departure). In this case, after receiving the link to the form, you must complete the required data, and after generating the boarding card (it will be sent to the indicated mail), print it and take it to the airport.

Attention! The card can be printed immediately after receiving the e-mail or saved in the portable memory (pen drive, smartphone, portable disk, etc.) and printed at a later date, but necessary before the approach to check-in and passport control or security at the airport! The printed card should be taken with you at the airport with the identity document used for check-in. The lack of it results in the necessity of paying a high penalty fee and in extreme cases even refusing to board the plane.

I can't check-in. What to do?

  • Check if a new flight schedule and a new check-in link have been sent to your e-mail address.
  • If the booking concerns a larger group, you shouldn't check-in more than several passengers at the same time. If there are too many passengers, when entering data from documents, the duration of the session may end. It's related to the security of your data.
