Thanks for the info. I wish Frontier would publish an official position. Maybe they prefer the ambiguity?

I forgot to mention that the flight attendant on the Lynx flight was really nice about it. She wasn't sure about the policy but wanted to err on the side of caution.

I think its funny that people can use laptops, but I can't use my GPS. The GPS actually emits less electronic interference than a laptop - and that's just the electricity. Just think how many people are using laptops without turning off their wireless transmitters! My GPS transmits nothing, but because it looks kinda like a cell phone, I can't use it.
