I guess I never said I thought it was a bad idea. It's a GREAT idea! It just seems to me as though whoever designed it, perhaps, didn't check it out while seated in the back seat of a cab/car - perhaps even at night in a dark car! I think if they did, they would have made the Delta name, a little bigger and prominent - that's all!
For sure, it's a very cool, eye catching ad - AND useful tool - for today's tech-oriented crowd, who make frequent travel decisions!
