Big intl AD, SLOT coordinated, PPR, mandatory handling, etc. To fly to/from Sofia you have to have: 1. Bulgarian CAA permission. You have to send the application form in 24hrs before entrance Bulgaria. Check this page - https://www.caa.bg/en/category/650/3740 2. SLOT REQUEST for GA. Check this page: https://www.sofia-airport.bg/en/business/airlines/slot-coordination 3. Handling (mandatory). With AOPA (any country) - it cost just 18euro. Send them a standard handling request to [email protected] So, a bit overcomplicated for GA, but as it is. ATC friendly and patient, ground staff very friendly, but sometimes they are a bit confused with the size of PA28. For example -they send to us whole passenger bus ;-) AVGAS100LL with no problem, fast and "full-full"
