Surging travel demand saw Ryanair carry 14.2 million passengers last month.
Numbers rose from just 1.04 million in April 2021 with the load factor improving by 24 percentage points to 91%.
This came as Europe’s largest budget carrier operated 82,600 flights in the month, which included the Easter travel peak.
The recovery came after traffic levels were hit by the Covid Omicron variant in December, January and February.
March traffic was damaged by the Russian invasion of Ukraine on February 24 with 2,000 flights cancelled due to airspace closures.
The April figure gave Ryanair a rolling annual total of 110.2 million passengers against just 28.5 million in the previous 12 months.
The increase followed rival Wizz Air reporting a 543% year-on-year rise in carryings in April to more than 3.6 million passengers.
