Much to tell you.  This is a Latvian airline, but the card was mailed from Lithuania in 2013 with stamp and partial Vilnius postmark.  If the aircraft registration number is YL-BDC–we think so–this is a Boeing 757 – MSN 26253, first delivered to Iberia Airlines in 1999 (as EC-HDU) with intermediate stops at Audeli, Air Baltic, and Tonle Sap Airlines before returning to Air Baltic in 2013.  Grade: 1
