Does anyone have any tips on the best way to book an open jaw flight from Boston to Ljubljana and then coming home from Dubrovnik back to Boston?
Hi, Angela.
You're easiest bet for Ljubljana/Dubrovnik would probably be to fly into a closer "hub" or bigger city like Venice, or Vienna, and just make a loop or open jaw them.
If that doesn't work for your plans, you can book via Lufthansa out of Boston (others will fly it, but you wind up being on 4-5 different airlines, and paying more. yikes!)
If you can leave from NYC (if you're up for the drive) you can do it with only 1 connection each way.
