Jet2CityBreaks is offering 22kg of check in baggage free of charge to customers booking city break packages to any of its 30 city break destinations.
It was previously offering free check in baggage to package holiday customers only.
The airline claimed it was offering up to a third more than other airlines, plus a free 10kg hand luggage allowance.
Head of trade Alan Cross said: "Customers taking city breaks have told us that having so much baggage allowance makes a big difference, so we want to make their city break even more enjoyable by providing that allowance free of charge."
