Chicago - Ft. Lauderdale $89 Roundtrip for Late Summer Travel

This fare is in United's basic economy cabin, which limits you to a small carry-on that will fit in the seat in front of you, if you require more baggage spring for the standard economy option for $138 or stick with the basic and check a bag, it will all total $50 more.

Boston - Brussels $333 Roundtrip for Fall 2019 Travel

Yesterday, upstart low-cost-carrier Primera Air added Brussels (BRU) to its list of nonstop options to U.S. based travelers. These flights will commence in May and June of 2019, but to find the best prices you'll have to wait until the September and October shoulder season to see the lowest rates. Searching in that travel window, you can travel on the only nonstop option from Boston to Brussels for $333 roundtrip. Keep in mind that Primera is a no-frills airline and just about anything extra comes with a price tag, even so, these new flights are a solid one-way option or for those who can travel light. Searching on Primera's site, I found seats departing BOS on Tuesday, September 10 and returning from BRU on Friday, September 20, 2019.
