Air Canada, Lufthansa, Air France, United and various other airlines have round-trip flights from Dallas (DFW) to Milan (MXP) for $520-$559 with a connection. Flights February, March, and November. Departures on Monday, Tuesday, Wednesday, and Sunday. No Thanksgiving dates.
Lufthansa “Light Fares” allow for a carry-on bag (17.6-lbs @ 21.6 x 15.7 x 9 inches) and also a very small personal item such as a laptop bag (11.8 x 15.7 x 3.9 inches). The weight limit will probably be the limiting factor for those of you who wish to avoid bag fees. Prioritizing heavier items in your “personal item” may be a good way to lighten your carry-on bag. You can avoid seat selection fees by accepting the randomly assigned seat at the gate.
