The experience of actually flying with them may be OK but the booking experience was so bad that we gave up trying to get tickets. If your legal name is too long then the website will say that the total number of characters of your name and date of birth together is too long and require you to change them before you can book. However who would do that when it's known to be essential that your ticket matches exactly your travel documents and legal name. We tried booking the tickets through an agent website as well instead of directly and the agent website said 'airline policy limits the length of your name' so if your name is too long you can't be a customer? Tried to call them on a Bulgarian number - no answer, they cut the call off. Overall we've given up perhaps a lucky escape!
