Short answer: Yes.

FitsAir offers light snacks, refreshments and a buy‑on‑board meal service (they obtained approval for in‑flight catering in January 2024). You can buy snacks and meals on board (and there’s a buy‑on‑board meal option referenced in their fare information). For exact menu items, prices and whether pre‑ordering is available on your specific flight, check FitsAir’s inflight menu or contact their customer care. (FitsAir.com)
