I bought my wife and I tickets on Vueling for flights Madrid-Barcelona and return. I bought 1 checked bag for each of us on both flights, but didn'[t realize till later that if I'd purchased their Optima fare instead of the Basic fare, the luggage was included. I've messaged them several times and just get back an automated response to look into buying an Excellent fare, without any response to my question if I can keep the same flight and just change to the Optima and get a refund on the difference between the higher Optima fare and the charge for the luggage on the Basic fare.
If that's not possible, I also asked them if we can get a refund, if we don't have a need for one of us to check a bag, even though we've already paid for it. Does anyone have experience or insight with Vueling on this?
