Martinair flies from Orlando and Miami and they are pretty cheap. I don’t know if it would be worthwhile, but there are lots of really cheap fare sales down to Orlando right now for late Spring and early summer. It might be worth checking out, especially if you can fly midweek or at an odd (cheap) time. I flew down there in the summer from Rochester for $89 each way, and then took Martinair to Costa Rica. This saved me about saved about $250. But because I live in Rochester I always need that flight into a “hub” anyway. It might not be as good for you if you can drive to JFK. Just a thought.  JK

ITA found $840 with Aer Lingus + other airlines to AMS and back from BRU. Cheapest nonstops are over $1000. Nearby: Cologne comes up $880.

ITA also found JFK-SNN at $492 roundtrip, total, nonstop flights with Delta. From SNN-Charleroi (Brussels “south” served by Ryanair), €11 with tax. If I recall, you can get an “all Belgium” train ticket for something like €10 per day—might be worth it, esp. if you wanted to go beyond Brussels, anyway (Antwerp? Brugge?). Unfortunately, there isn’t a lot of service to Shannon, so getting back cheaply would have to be from Weeze airport in Germany. For only a 1 week trip, this might be more trouble than it’s worth.

Thank you for your help.

Any help finding inexpensive round trip airfare from Chicago (ORD) to Lisbonon (LIS) on June 29 and returning 14 to 15 days later would be greatly appreciated. I’m also lookin for a cheap hotel.
Thanks,
