Air Canada and Lufthansa have round-trip flights from Denver (DEN) to Lisbon (LIS) for $494-$516 with a connection. Flights March, April, October, November, December, and January. No Friday departures. Very few extended weekends available. Holiday blackouts.

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.

If you use the Aeroplan® Credit Card, you and up to 8 companions can receive their first standard checked bag for free when travel originates on an Air Canada flight.

You can usually save more money by booking your flight+hotel together as a package instead of separately.
