Budget Travel from Paris to Lisbon

Fly, for price and speed. In a quick search I saw EasyJet CDG to LIS for $120 one way, 2hrs 40mins, use this search engine Sky ScannerTrain is bad, almost 24 hours of train time.

It sounds like an exciting trip you're planning!

And a third is flylc.com, but don't use their booking engine...check the airlines' websites directly. When looking at budget airlines be VERY CAREFUL about baggage restrictions and limits, and check-in times.....they allow you no margin for error, without paying a hefty price, or being denied boarding on your flight. And check the "big boys" as well....TAP, Air France, etc. On routes where they have competition from the discounts, they will often match the fares, and have more convenient schedules to boot.

Thank you ALL!!!
