Short answer — FitsAir mainly operates Airbus A320-200 aircraft. As of mid‑September 2025, its active fleet is reported as three A320‑200s (used for passenger services and some converted/wet‑leased freighter operations). (en.wikipedia.org)

Additional context:

• FitsAir has used A320s both as passenger aircraft and as passenger‑to‑freighter (P2F) or wet‑leased freighters. (iatanews.com)
• Historically the airline also operated types such as ATR‑72, Cessna 208 Caravans and various Soviet types (Antonov, Il‑18) — these appear in its historical fleet but are not listed as the main active types in current fleet summaries. (en.wikipedia.org)

If you want, I can list the current registrations, seating configs, or recent wet‑lease/freighter activity.
