Airfares fell by 19.3% in November in the steepest plunge for the month in more than 20 years.
The reduction compared with a fall of 13.9% a year ago, according to figures from the Office for National Statistics.
“Fares usually fall in November, but the drop in 2024 was the largest November fall since monthly price collection began in 2001 and follows a relatively high figure for October,” the ONS said.
“The movement was largely driven by falls in fares on European routes.”
The figures emerged as the ONS revealed that UK inflation rate rose to 2.6%, up from 2.3% in the year to October.
Rises in the cost of fuel, clothing, housing and vehicles helped contribute to the overall increase.
“The largest upward contributions to the annual Consumer Prices Index inflation rate in November 2024 came from the housing and household services, restaurants and hotels, and recreation and culture divisions,” the ONS noted.
“There were partially offsetting downward contributions from transport, and furniture and household goods.”
