In principle, a Ryanair Boeing 737 MAX 10 could operate from Leeds Bradford Airport (LBA) to Dublin Airport (DUB) safely, provided the aircraft is certified for service and the specific flight meets all the airport, runway, weather and performance requirements.
The Leeds–Dublin route is relatively short, so the aircraft would not need anything like its maximum range. The main question is whether the MAX 10 could take off from Leeds Bradford's runway with its passengers, baggage and fuel load under the conditions on the day.
There is one important distinction: being technically capable of operating the route is not the same as confirming that it could operate every departure at maximum weight.
Why Leeds Bradford is the key factor
Boeing 737 MAX 10
Length: 43.8 m
Maximum seating: up to 230 passengers
Maximum take-off weight: about 89.8 tonnes
Range: approximately 3,100 nautical miles
Source: Boeing technical specifications.
Leeds Bradford Airport
The airport has a runway approximately 2,250 metres long. Its elevation, gradients and local weather conditions make take-off performance particularly important.
The MAX 10 is larger and heavier than the 737-800 that Ryanair commonly operates. Boeing's own runway-performance charts show that the runway length required depends on aircraft weight, temperature, wind and runway conditions.
Would it manage the flight?
My verdict: I would expect the Leeds–Dublin route to be a plausible mission for a Ryanair 737 MAX 10, but I would not claim it could depart Leeds with all 230 passengers and full fuel in every condition without a detailed aircraft performance calculation.
