About U5
U5 is a regional carrier built around Chisinau (RMO), the capital of Moldova — one of Europe's least-visited countries and, honestly, one of the most underrated. With 40 non-stop routes spread across 21 airports and a total network stretching 77,084 km, this isn't a massive operation, but it punches above its weight for travelers moving between Eastern Europe and the western Mediterranean. The route map leans hard into Spain and Greece, which tells you exactly who's buying tickets: Moldovan diaspora, seasonal workers, and sun-seekers. Think regional, point-to-point, no-frills positioning rather than legacy carrier comfort.
Why fly U5?
The honest answer is access. If you're routing through or out of RMO, U5 gets you to places that bigger carriers don't bother serving directly. Six routes into Spain, six into Greece — that's real coverage for a carrier this size. The RMO-TFS run at 4,450 km is the longest haul in the network, putting Tenerife South within direct reach of Moldova, which is genuinely useful if you're avoiding a connection through a congested hub like MAD or ATH. For diaspora travelers especially, these direct links save hours. Prices on thin Eastern European routes tend to stay competitive simply because demand is specific and loyalty is high. If the route exists on U5, it probably doesn't exist anywhere else nonstop.

Tips for booking U5
Book early on the Spain and Greece routes — those six-apiece corridors fill up fast in summer, and U5 isn't running daily frequencies on most of them. RMO is the clear stronghold with 20 routes, so if you're connecting, build your itinerary around Chisinau rather than the secondary hubs like ALC, BCN, or CFU, which each hold just a single route. Don't expect alliance perks or points earn with major programs — generalise your expectations toward a standalone regional carrier. Check baggage allowances before you book, as budget-adjacent carriers in this segment often unbundle everything. First-time flyers should confirm check-in deadlines; smaller hubs move fast.
