I have a flight with Lufthansa Airlines, a basic economy flight from Frankfurt to Montreal.
I ask if a bag of a type Samsonite Laptop Backpack/Wh is allowed on the plane, knowing that its dimensions are 39 x 24 x 55 cm. And the dimensions allowed by Lufthansa are 40 x 23 x 55 cm.
Will it be considered an extra Checked baggage ? Will I pay additional fees?
