Everything about Ryanair’s ironing-board seats, tiny legroom, and poor catering seems the antithesis of private aviation. Yet, the airline operates a secret fleet of five Bombardier Challenger 3500 planes. These aircraft aren’t for luxury passengers. Rather, they carry parts and mechanics to deal with urgent aircraft maintenance needs. Ryanair has found that an expensive private flight is less costly than paying compensation to passengers for extended delays.

You can use the Simple Flying Live Flight Tracker to try to spot these jets in service. The registrations to look out for are M-ABSU, M-ABTE, M-ACOR, and M-ASBA. The airline also has a Learjet 45XR from its legacy private jet fleet. You can use the flight tracker to look for this one too. It has the registration M-ABGV. Our tracker was built specifically for avgeeks, with tools that go way beyond what you can usually expect from a flight tracker.

Why Ryanair Uses Private Jets?

The factor that makes private jet ownership worthwhile for Ryanair is the enormous amount of compensation European airlines have to pay out because of the EU261regulations. A cancellation or extended delay forces a compensation payment, as well as helping passengers with accommodation, meals, rebooking, and more. Further costs come from crew disruption and airport costs. Aircraft Broker Program writes that the costs can exceed €100,000 ($116,000).

Delays and cancellations can be averted by flying out mechanics, parts, or flight crew, depending on what has caused the problem. The quickest and most cost-effective way to do this is with a small business jet. Aircraft Broker Program estimates that the costs of operating such a flight will be between €10,000 ($11,600) and €20,000 ($23,200).

Another cost to factor in is the acquisition cost for these Bombardier Challenger 3500 jets. Aircraft Charter Service writes that a new Challenger 3500 costs $26.7 million. Therefore, all four jets likely will have come to a price point of under $100 million once any deals done are factored in. Given that these aircraft help keep a vast fleet of 340 Boeing 737 aircraft in the skies, it’s not surprising that Ryanair concluded the ownership is worthwhile.

The four Bombardiers have been acquired over the past 18 months. The first jet, the Isle of Man-registered M-ABSU, was delivered in March 2025, ch-aviation reports. It was delivered from Montréal-Pierre Elliott Trudeau International Airport (YUL) to Dublin Airport (DUB), before continuing to London Stansted (STN).

The second Challenger 3500 was delivered the following month and the third the month after. It added the fourth aircraft in April 2026. Ryanair accepted each aircraft brand-new, in line with the carrier’s commercial aircraft acquisition policy, which tends to buy new jets directly from the manufacturer. The table below shows specifications for the Bombardier Challenger 3500, making use of data published by Bombardier:

Range

3,400 nautical miles (6,300 km)

Typical capacity

10

High-speed cruise

Mach 0.82

Typical cruise speed

Mach 0.80

Maximum operating altitude

45,000 feet

Powerplant

2 x Honeywell HTF7350 turbofans producing 7,323 lbf (33 kN)

Wingspan

69 feet (21 meters)

Length

68 feet, 8 inches (20.9 meters)

It initially wasn’t clear what service these aircraft would perform when they first arrived. However, the airline’s legacy fleet was used primarily to fly parts, engineers, and reposition flight crews, so it was assumed they would use the aircraft the same way. That has come to pass. A modern fleet of business jets performing such functions is vital because Ryanair operates decentralized point-to-point operations, rather than always flying out of a few hubs. That means its crew, engineers and parts remain spread over a large area.

Ryanair’s Challengers are not the first time it has used private jets. It previously operated three Learjet 45XRs, acquired from 2012 to 2015, and one Learjet 45 bought in 2022. The planes were between 12 and 25 years old when the carrier acquired the Challengers. One of the 45XRs remains in service. These jets have the registrations ABEU, M-ABGV, M-ABJA, and M-ABRB. These aircraft were distinguished from Ryanair’s standard planes by their different livery and, sometimes (though not always), by the call signs FR1, FR2, and FR3.

The table below shows specifications for the Learjet 45XR. It makes use of Guardian Jet’s brochure for the aircraft:

Typical capacity

8

Range

1,690 nautical miles (3,130 km)

Cruising speed

460 knots

Ceiling

51,000 feet (15,545 meters)

Maximum takeoff weight

21,500 lbs (9,752 kg)

Wingspan

47 feet, 9 inches (14.6 meters)

Maximum asking price

$4,600,000

Operating cost per hour

$3,565.56

As with the new Challenger 3500s, these jets had an Isle of Man registration. They were leased from Aviation Leasing (IOM) Limited, as reported by AeroTime.
