ok - im buying everything on cc's as i want yet another free first class trip to europe...

here is my question, i could do the math but am thinking someone has done it already.

delta biz skymiles card earns 1 mile for each $1 spent
chase priority club card earns 1 point for each $1 spent

which is more valuable? since i need hotel rooms and the flight, both are equally valuable.

I am thinking the skymiles are worth more but am wondering...

Thanks,
Allen
