I am a total newbie so, I apologize in advance for any inconvenience . I am hoping to get some input .My plan is to travel to Europe(London) first so, that I can reduce cost . I have a platinum Amex with 70k points would it be wiser to transfer this points to an Airline or a hotel chain ?This trip is for 2 leaving either from NY/NJ depending on the cost to London staying for a day or two and experience London then Mykonos/Santorini and back to NY/NJ. I also have 4x 100 AA gift cards.Any itineraries would help or even advise if this is ideal and what are my best options since I have to travel in July which is the highest season for sky rocketing prices.
