Swapping Verizon iPhone 6's time period?

I'm THINKING that I may want a 6+ instead of my 6.

How long will Verizon let me swap my new 6 for as 6+ (and pay the difference) after I purchased it?

I believe it's 14 days.

Yup. 14 days, and for a voluntary switch (vs. a replacement for a defective iPhone) you will probably have to pay both a restocking fee and a new activation fee on the 6+.
