A fifth daily service is to run between Heathrow Airport and Berlin-Tegel by Bmi.
The extra flight is designed to give business travellers more choice when flying between the two cities.
The additional frequency, which begins on June 21, will depart from Heathrow at 07.10 and arrive in Berlin at 10.00.
The return will depart Berlin at 11.05 and arrive into Heathrow at 12 midday.
Flights will be operated using an Airbus 319 aircraft, with business class and economy cabins, both offering complimentary food and drink.
The carrier also operates daily flights from Heathrow to Berlin at 09.20, 14.45, 17.50 and 19.45.
Return flights leave Berlin at 07.25, 13.10, 18.10 and 21.20 with return fares starting at £99.
Sales and marketing director Katherine Gershon said: "These extra services reinforce Bmi’s leading position as the carrier of choice for business travellers.
“Due to overwhelming demand, our new services mean that London-based customers can reach Berlin even earlier for business meetings.”
