Passengers using Manchester airport rose by 4.1% to 2.1 million in June over the same month last year.
It was the 13th consecutive month of year-on-year growth for the northern gateway.
International scheduled traffic rose by 9.4%, helped by new services including EgyptAir to Cairo and increased frequency by TAP Air Portugal to Lisbon.
Airlines such as easyJet, Ryanair, Monarch, Jet2.com, Germanwings and Norwegian continue to grow from Manchester.
Virgin Atlantic also announced plans to offer 30,000 extra return seats to Orlando from Manchester in summer 2014 with daily flights and twice-daily services on Tuesdays, Wednesdays, Fridays and Saturdays.
Ken O’Toole, chief commercial officer for airport owner Manchester Airports Group, said: “We’ve seen over a year of continued month-on-month growth now and the next few months will provide an additional boost as over 14 million passengers are expected to use Manchester airport during the summer.
“We’re entering the full swing of the summer season and are expecting a further surge in passengers once the schools break up as millions of people fly away for a well-deserved break.”
The top five foreign destinations for this summer are Palma, Amsterdam, Dubai, Alicante and Tenerife, with August 23 expected to be the busiest day of the summer when 84,000 passengers are due to travel through the airport against 80,000 on the same day last year.
