About CU
Cubana de Aviación — operating under the IATA code CU — is Cuba's state-owned national carrier, which tells you most of what you need to know about its business model: this isn't a scrappy low-cost outfit chasing ancillary revenue, and it's not a legacy carrier with a points program worth collecting. It's a government airline doing government airline things, connecting Cuba to a small but deliberate international network. Sixteen non-stop routes across seven airports, with HAV as the clear operational center. The network spans just over 60,000 km in total, which sounds impressive until you realize how concentrated that mileage gets on a handful of long-haul routes.
Why fly CU?
Honestly? You fly CU because it's often the most direct option to Cuba, full stop. Twelve of its sixteen routes land in Cuba, so if you're visiting the island rather than just transiting through it, the routing logic is hard to argue with. The HAV-MAD run at 7,461 km is the network's centerpiece — useful for European travelers connecting through Madrid who want a straightforward transatlantic option. Buenos Aires (EZE) gets two routes, which matters for South American travelers who'd otherwise be stringing together connections. Don't expect a premium product in the conventional sense. Fly CU for access, not for the experience. That's a fair trade if your destination happens to be somewhere the rest of the world doesn't fly nonstop.

Tips for booking CU
Book early and have a backup plan — CU's schedule reliability has a complicated history, and the network is thin enough that irregular operations don't have obvious recovery options. HAV is your safest entry point with six routes, but if you're connecting through SCU or CCC, understand those are smaller hubs with fewer alternatives if something goes sideways. The Spain routes are worth watching for pricing if you're Europe-based. Don't assume alliance reciprocity for lounge access or miles — CU operates outside the major alliance structures. Check your specific fare class before assuming any flexibility on changes. Bring patience, and read the baggage rules carefully before you pack.
