Men Are Helpless, Part 380,146

A few questions:

If Dave and Mandy are going on vacation together, why would they be searching individually online for resorts, etc? Isn't this something couples generally do together?

Is the narrator telling us that Dave stayed up all night searching websites that he actually missed the flight, so Mandy went on vacation by herself? Does this really happen?

The narrator tells us that Dave "misses flights." That's plural. So Dave REGULARLY obsesses over travel websites all night, including the nights before they are scheduled to leave? This makes no sense- what is he looking for online if the tickets are booked already?

Or are we being told that Dave stayed up all night searching websites and was never told that his girlfriend had found the perfect vacation- so she went without him? Is that it?

Is the message of this commercial really that if you don't just assume that your girlfriend is 100 percent smarter than you are and should just be allowed to make all the travel arrangements, she's going to dump you for some local she meets while on vacation by herself, or while you are asleep back at the hotel?

The company being advertised is called Kayak.com. Why don't I see any kayaks in this ad?

I mean, what the hell?
