We had to pay $45 Euros each for our 2 checked bags as we thought they were free. The hotel desk in Madrid checked us in for our flight and we thought our bags were free so did not pay for any. We found out from the airline if we check the bags in online before the flight 25 Euros each. I Am NOT VERY HAPPY with EXPEDIA for not making this clear. So we have an added cost for our flight from Spain to Rome round trip of 140 Euros. WOW!!!
