I need help making the best use of MR points (or American, Delta or Hawaiian) for a multi destination trip. Happy to fly business if the difference isn't much but mostly happy to make the most of the points used.
I'm flying from NYC to Barcelona on August 4th preferably on an overnight flight.
On August 9th flying from Barcelona to Dublin.
On August 14th flying from Dublin to NYC.
I figure it would probably be the best value for me to pay cash for the flight from Barcelona to Dublin since it's so short. What are my best options? I also have American, Delta and Hawaiian miles that I can use for this trip. What's my best plan?
