Buzz

A Ryanair flight lands, the tail is dark blue, the flight number starts with FR – and yet the rear fuselage shows an SP-, not an EI-. Then you most likely have Buzz in front of your lens, the Polish airline of the Ryanair Group. For passengers, it is practically invisible; for spotters, it is one of the most interesting sisters in the Ryanair universe. On this page, you will learn where Buzz comes from, what it flies and how to reliably tell it from Ryanair DAC.

Buzz at a glance

Buzz is a Polish airline headquartered in Warsaw and belongs entirely to Ryanair Holdings. It flies two kinds of traffic: scheduled flights sold in the Ryanair network and charter flights to vacation regions. The company behind it is still called Ryanair Sun S.A. – the name under which it all began.

Within the group, Buzz is the airline for Poland and large parts of Central and Eastern Europe. The aircraft and crews are stationed at bases in Poland, such as Krakow, Katowice, Gdansk, Poznan, Wroclaw and Warsaw Modlin, and also at bases in other countries of the region. Which bases are currently served by Buzz and which by Ryanair DAC shifts again and again; the basic rule remains, however: where Ryanair is stationed in Poland, Buzz is usually behind it.

From Ryanair Sun to Buzz: the history

Start as a charter airline

Ryanair founded the company in July 2017 under the name Ryanair Sun. The idea: offer charter flights for tour operators from Poland – a market that is traditionally strong in Poland and shaped by companies such as Enter Air. The Polish aviation authority granted the operating license in April 2018. The first flight went from Poznan to the Greek island of Zakynthos at the end of April 2018.

In the first summer, the fleet was manageable. A single Boeing 737-800 with the registration SP-RSA flew charter rotations from Warsaw Chopin in 2018. In the first year of operation, the program consisted mainly of package holiday flights for Polish operators.

Taking over Ryanair’s operations in Poland

As early as fall 2018, the role changed fundamentally. In September 2018, Ryanair announced it would give up its own Polish bases; Ryanair Sun took over scheduled operations in Poland instead. At the end of October 2018, SP-RSA switched from charter flights at Warsaw Chopin to scheduled flights from Warsaw Modlin – on behalf of Ryanair. In the following months, more 737s moved from the Irish to the Polish register.

That turned the small charter offshoot into the airline that flies a large part of Ryanair’s offering in Poland. For spotters, that marked the beginning of the era in which a “Ryanair” in the sky was no longer automatically an Irish aircraft.

New name: Buzz

In early 2019, Ryanair announced the renaming to Buzz. Since late October 2019, the airline has flown under its new name and logo. The name has a backstory: Buzz was already the name of a British low-cost airline that Ryanair took over from KLM in 2003 and then merged into its own operations. So Ryanair fetched the brand name from its own archive.

What remained is the callsign. On the radio, Buzz still identifies itself as “MAGIC SUN” – an audible reminder of the Ryanair Sun days. If you run a scanner at the spot, the callsign is a quick confirmation that no Ryanair DAC aircraft is arriving at the moment.

Codes and callsign

With Buzz, a close look at the codes is worthwhile because in everyday use they diverge:

• IATA code RR: Buzz’s own two-letter code. In the Ryanair network, though, the group mostly sells flights under FR flight numbers, so you rarely see RR in everyday use.
• ICAO code RYS: appears in the air traffic control flight plan and thus on many flight trackers. RYS is your most important hint that Buzz is flying.
• Callsign MAGIC SUN: how the crew identifies itself on the radio.

That means: the departures board at the airport shows “Ryanair” and an FR number, while the tracker shows an RYS callsign. If you learn to connect the two, you place every group aircraft correctly. How to use ADS-B data for that is shown in the guide to flight tracking for spotters.

The fleet: pure Boeing 737

Like the whole group, Buzz consistently relies on the Boeing 737. Three variants are in service:

Type	Seats	Role at Buzz	Spotter note
Boeing 737-800	189	Backbone of the fleet	Classic 737 Next Generation, many aircraft come from the Irish register
Boeing 737-8200	197	MAX generation, growing share	Additional emergency exits behind the wing, serrated engine nacelle edge
Boeing 737-700	148	One-off	Shorter than the 737-800 – a real rarity at Buzz

The exact number of aircraft fluctuates because Ryanair shifts aircraft back and forth between the group’s airlines. Public fleet overviews give around 75 to 80 aircraft for 2025 and well over 80 for mid-2026. The lion’s share is still the Boeing 737-800, plus a growing number of Boeing 737-8200s, the densely seated Ryanair version of the 737 MAX 8.

A special case is the single Boeing 737-700. It is shorter, has fewer windows and offers only 148 seats. If you collect Buzz registrations, it is one of the aircraft worth searching for specifically. The manufacturer of all types is Boeing.

737-800, 737-8200 or 737-700? How to tell them apart

At Buzz, you have the chance to see three 737 variants under the same flight number family. These features help:

Be careful with the winglets: Ryanair is retrofitting some of its 737-800s with split-tip winglets that resemble those of the MAX. The engines and the additional emergency exits are more reliable. You can find a detailed comparison of all series in the guide Telling the Boeing 737 Original, Classic, NG and MAX apart.

How to recognize Buzz

At first glance, a Buzz aircraft often looks like any other Ryanair: white fuselage, dark blue tail. Many aircraft wear the group’s standard livery with the yellow harp, and there are also aircraft in their own Buzz livery. How airlines build such designs is explained in the article Livery design explained. Which variant is flying where at the moment cannot be predicted – the livery alone is therefore not a reliable feature.

The registration is reliable. Polish aircraft carry the prefix SP-, while Ryanair DAC carries EI- and Malta Air or Lauda Europe carry 9H-. How registrations are structured and why so many aircraft are registered in Ireland or Malta is explained in the articles Understanding aircraft registrations and Offshore registrations and leasing.

Charter and scheduled: two faces of one airline

On its own website, Buzz explicitly describes itself as an airline for charter flights to vacation regions and for scheduled flights within the Ryanair Group. There are historical reasons for that: Ryanair Sun was founded for exactly this. Poland has a large package holiday market, and tour operators charter aircraft for entire seasons – typically toward the Mediterranean, the Canary Islands or North Africa. How charter and scheduled traffic differ is explained in the article Charter flights vs. scheduled flights.

For spotters, that makes Buzz more versatile than a pure Ryanair copy. Charter rotations often run at different times and on different routes than the Ryanair network, and they also take Buzz aircraft to airports where Ryanair otherwise hardly shows up. In summer, it is therefore worth a look at the departures of Polish operators. A side detail: Buzz shares the role of charter airline in Poland with Enter Air, which also operates Boeing 737s – a direct comparison at the same airport is appealing.

Spotting Buzz: where and when

Your best chances are at the bases. In Poland, these are mainly Krakow, Katowice, Gdansk, Wroclaw, Poznan and Warsaw Modlin. Outside Poland, Buzz bases were most recently reported in Prague, Budapest, Bratislava, Vilnius, Riga and Sofia, among others. The list changes with every schedule change, so check it before a trip.

If you go to Prague, the viewing platform near Kněževes is an official spot; in Budapest, the Aeropark at the airport offers photo opportunities next to historic aircraft. In Krakow, a detour to the Polish Aviation Museum is also worthwhile. At Polish airports, you meet Buzz together with the Polish national airline LOT and the big low-cost competitor Wizz Air – handy for a comparison on the same day.

In Germany, Buzz remains more of an occasional sighting. It shows up when a flight comes from a Buzz base or when Ryanair reschedules aircraft within the group at short notice. That is exactly why the tracker check is worthwhile: if you know which FR flight is running with RYS today, you stand at the fence at the right time. How to estimate the landing direction in advance is covered in the guide to the runway direction in use at airports. And if you are just starting out, Plane spotting for beginners helps.

Common mix-ups

• Thinking every harp is Ryanair DAC – Buzz often flies in the same look. The SP- registration decides.
• Equating the FR flight number with the airline – the flight number shows the seller, the ICAO code RYS shows who is really flying.
• Confusing Buzz with the British Buzz – the old British low-cost airline was absorbed into Ryanair’s operations after Ryanair’s takeover in 2003; today’s Buzz is a Polish founding from 2017.
• Thinking MAGIC SUN is another airline – the callsign dates from the Ryanair Sun era and belongs to Buzz.
• Confusing Buzz and Enter Air – both are Polish, both fly 737s and charter, but Enter Air is an independent leisure airline with its own livery.
• Logging the 737-700 as a 737-800 – the shorter fuselage is the hint to the fleet’s rarity.

Conclusion

Buzz is the airline you easily overlook at the spot because it hides behind Ryanair flight numbers and often behind the Ryanair livery, too. But there is a story of its own behind it: founded in 2017 as the charter offshoot Ryanair Sun, operating under a revived name since 2019 and today the Polish pillar of the Ryanair Group. If you pay attention to the SP- registration and the ICAO code RYS, you turn one more “Ryanair” into an entry of its own – and with the single 737-700, you even have a real collector’s item in your sights.
