I am planning a trip to Europe departing Buenos Aires near 22nd May, returning ~13 June. The plan is to fly to Rome - visit Italy and Greece, then travel via road/train to Spain and end up in Portugal. On the way home from Lisbon have a long layover in London to visit the city. The best price I have found so far is ~$1250 USD p/p the outward journey on Iberia through Madrid the return on British Airways through London. Can anyone find a better price for that time period with no crazy layovers? I only have 55,000 points with United and 40,000 with Qantas so I don't think they can be utilized in this situation?
