Ryanair carried 11.5 million passengers across its route network during December.
That figure marks a 21% increase on the 9.5 million people it carried during the same month in 2021.
Load factor – which measures how full its planes were – also improved year-on-year in December, rising from 81% in 2021 to 92% last month.
Ryanair has recently been aggressively growing its routes out of Dublin, Shannon, Belfast, Cork and Ireland West Airport Knock ahead of the summer 2023 season.
