Online check-in Eastern Air Lines - https://www.check-in.site

As an AI language model, I can provide you with some general information about online check-in procedures for airlines, but please note that I do not have access to real-time information or specific details about Eastern Air Lines after my knowledge cutoff in September 2021. As of that time, Eastern Air Lines had ceased operations in 1991, but there have been reports of a new Eastern Air Lines starting operations in recent years. However, I do not have updated information on their current status or procedures.

For most airlines, including those that offer online check-in, the process typically involves the following steps:

1. Visit the airline's website: Go to the official website of Eastern Air Lines or the specific website of the new Eastern Air Lines if it exists.

2. Find the check-in section: Look for the check-in or manage booking section on the airline's website. This section is usually located prominently on the homepage or in the main navigation menu.

3. Enter your booking details: Provide the required information, such as your booking reference number, last name, and departure city. These details are usually found on your booking confirmation or e-ticket.

4. Select the passengers: If you're traveling with others, you may need to select the passengers you want to check in. This step may vary depending on the airline's online check-in system.

5. Choose your seat: Depending on the airline and availability, you may have the option to select your seat during online check-in. If seat selection is not available, you will usually be assigned a seat at the airport.

6. Review and confirm: Verify all the provided information, including flight details, passenger names, and contact information. Make any necessary changes or additions before proceeding.

7. Obtain your boarding pass: After confirming your check-in, the airline's website should generate your boarding pass. You may receive it via email, as a downloadable PDF, or through a mobile app if the airline provides one. Ensure you have access to your boarding pass when you arrive at the airport.

Keep in mind that specific check-in procedures and timelines can vary depending on the airline, airport, and the type of flight (domestic or international). It's always a good idea to check the airline's website or contact their customer service for the most accurate and up-to-date information regarding online check-in procedures.
