I’d appreciate some guidance and advice from someone with more experience with award travel than me.

I’ve booked a cruise for June-July 2027 that sails from and returns to Dover, England so I want round-trip Business Class trans-Atlantic tickets for myself and my wife from the U.S. to LHR or LGW. My nearest airport to my home is CVG. I’m looking for ways to maximize the value of my various miles and points, realizing that I may not have enough to cover the entire trip with points. I also realize that I may have to book positioning flights to/from my gateway cities.

I have Aeroplan (114K); Delta (100K); AmEx (170K) and Chase UR (25K).

I’m stuck on figuring out how to eat this elephant. What’s a good approach?
