The Latvian airline Air Baltic is currently struggling with a data breach. This means that web check-in is not available on many flights. The affected passengers must appear at the check-in counter at the respective airport with their ID. The carrier informs travelers by email that reservation data has been sent to other passengers due to a technical error. Put simply, this means that people who are not concerned with the confidential data have received a reservation confirmation from Air Baltic that they should not have received. To ensure that the tickets are not used improperly under a false name, the Latvian carrier is asking the affected passengers to appear in person at the check-in counter. For this reason, internet check-in is not available on many flights. The company emphasizes in a letter that there are no extra costs for using the counter check-in, which is requested. Air Baltic usually asks you to pay if you have not previously checked in via the internet. The airline also stresses that no payment data is affected by the data breach. Those recipients to whom reservation data was accidentally sent would not have access to credit card information and/or similar payment methods. Due to the data breach, additional services cannot be booked online. These can currently only be purchased by phone, email and at the airport counter. This is also for security reasons, according to the letter from Air Baltic.
