The figure was the first time the airport has experienced double-digit growth since December 2005.
In total, 549,489 travellers passed through the airport during the first month of the year, and long-haul traffic saw a rise of 23.8% compared to January 2013.
Paul Kehoe, Birmingham Airport’s CEO, says: “These January figures show that more and more people are realising the benefits of using Birmingham as an alternative to other airports to fly for business and leisure.
“This is a great start to 2014 and we look forward to offering even more choice this year as several new routes are launched and extra capacity is made available on key routes.”
Liverpool John Lennon Airport (LJLA) also saw a rise in traveller number of 5% in January compared to last year.
Robin Tudor, head of PR at LJLA, says: “It’s no surprise that low cost airlines Ryanair and easyJet with flights at great prices have been carrying more passengers to destinations with much better weather than we have seen here in the UK for some time.
“With the school half term rapidly approaching, we are expecting this trend to continue in the coming weeks too and our range of ski destinations are also perfect for any budding winter olympians.”
