About 4Y
4Y operates as a European-focused carrier with a network that punches well above what its name recognition might suggest. Built around Frankfurt FRA as its primary hub — with 56 routes radiating outward — the airline connects 63 airports across a total network spanning over 610,000 kilometres. Germany dominates the route map with 95 connections, but the reach extends meaningfully into Greece, Spain, and beyond, with a lone long-haul outlier stretching all the way to Mauritius. It's a network that reads like a carrier finding its identity: solidly European at its core, with ambitions that occasionally surprise.
Why fly 4Y?
The honest case for 4Y starts with coverage. If you're moving through central Europe — particularly in and out of FRA or MUC — the route density is genuinely useful. Twenty-three routes into Greece alone means you're not locked into Athens when you'd rather land on a smaller island. Spain gets 18 routes, which gives Mediterranean travellers real options. And then there's that Frankfurt-to-Mauritius run, FRA-MRU at 9,200 kilometres — one of the longest non-stops I've seen on a mid-tier European carrier. Whether that route suits your itinerary or not, it signals that 4Y isn't purely playing it safe. For travellers whose trips begin or end in Germany, this network offers a level of point-to-point convenience that avoids unnecessary connecting misery.

Tips for booking 4Y
Frankfurt FRA is where 4Y is strongest — 56 routes give you real flexibility if plans shift. Munich MUC adds a solid secondary option with 39 routes, useful if you're based in southern Germany. The Mombasa MBA and Harstad-Narvik EVE hubs each carry only 3 routes, so treat those as specialised access points rather than connection hubs. If you're eyeing the FRA-MRU long-haul, book early — single long-distance routes on smaller carriers fill faster than people expect. Check baggage allowances carefully before you fly, as policies can vary significantly across fare classes. Greece and Spain routes are the network's sweet spot; that's where frequency and timing tend to work most in your favour.
