Back in May United and Delta began offering low fares to Europe from American Airlines’ major hub, Dallas-Ft. Worth. Those fares disappeared, but now they have re-appeared. Austin and San Antonio are included. Many cities in Europe are available.
Departures from late August through the Fall and Winter to February 2017.
Some example round-trip fares from DFW: Barcelona $453, London $558, Paris $624, Casablanca (Morocco, Africa) $622. Austin and San Antonio are generally a little higher.
Expect other airlines to match these fares.
