I booked a flight from Lisbon to Madrid in September. 55 euros I did not think too bad.
I have a RS carry on bag and it should be light maybe 20 to 25 pounds. Will I get some unexpected charges for weight or size? I heard Ryan Air does that?
Vueling's policies are actually pretty liberal for a discount airline. Carryons can weigh up to 10 kilos (22 lbs) and can't exceed the usual measurements of 55 x 40 x 20 cm. You can also bring another item, such as a purse or briefcase. Checked baggage limit is 20 kilos (44 lbs)...8 Euro/kg surcharge after that.
