Norse Atlantic Airways has round-trip flights from Los Angeles (LAX) to Paris (CDG) for $308, NONSTOP. Flights August to October. No Tuesday departures. Extended weekends available. Origin/Destination reversible.
Norse Atlantic is a budget carrier. Fares do not allow for a free carry-on bag. Only a small personal item (17 x 14 x 8in) like a Jansport SuperBreak backpack is allowed without additional fee. You can avoid paying for seat selection if you accept the randomly assigned seat prior to boarding. Checked and carry-on bags cost between $45 and $70 each-way, depending on weight and size.
