Hello sorry if this is in the wrong spot but I'm looking for a little advice. My girlfriend and I live in Boston and were looking to do a trip to europe for 3 weeks and see maybe dublin, london, paris, barcelona, and maybe anywhere else in between if we can. This is where i get a little lost. Whats my best options to make it as efficent as possible regarding earning points. I just got approved for a jetblue card today which im excited about but i dont see much talk about jetblue when people talk racking up points. Any advice on best routes to see these places and gain points? Preferable airlines? Cheaper is better i dont mind taking economy flights, im in the military we dont make enough for me to fly like royalty! Thanks in advance guys
