Having flown Vueling a dozen times in the past three years, I am almost afraid to share how consistently positive these experiences have been, so fearful am I that future flights will be too popular. This is a wonderful way to fly between European cities, especially when time is an issue, and flights are sometimes less expensive than the train. We've flown Barcelona to San Sebastian, Granada to Barcelona, Rome to Barcelona, Palermo to Nice, Barcelona to Paris, etc. There have been slight delays, if any. Checked bags are delivered quickly. Staff is courteous. Booking on line is easy. Five stars!
