I have been researching flights to Europe, and I found a reasonable rate to Lisbon, Portugal. This is a flight from Dallas/Fort Worth airport to Lisbon, Portugal on United Airlines for $799 round trip. However, this fight does have two stops and takes 16 hours to get there. Also, there is another flight from Dallas to Milan, Italy for $751 round trip on American Airlines. The dates I used in the search is March 25, 2019 to March 30, 2019. If you are looking for a cheap flight to these places then this could be a good deal.
