Good luck running through an airport like this in a post 911 world. No hurry through security, no stranded kid.

Yelp would've gotten this store shut down long ago. There's no way they'd be allowed to keep the doors open while selling toothbrushes not approved by the American Dental Association.

Buzz's girlfriend would have made their relationship Facebook official long ago and there would be no need to hide her picture in a trunk.

Kevin would have had a lot less panic attacks about the basement because Peter McCallister and his seemingly limitless amount of money would have a modern boiler instead of a furnace from 1936.

A simple Google search would prove that Buzz was lying about the South Bend Shovel Slayer.

Kevin would have been able to review the family's pizza order online and known when it was being delivered so he could be there to get a slice of cheese pizza before Buzz ate it all.

The family would've had their tickets on their phone instead of getting them weeks in advance like some sort of domestic terrorists. That way they would've realized Kevin wasn't there.

Absolutely nothing in this scene would have happened.

Text messaging could have taken care of all the misunderstandings in about 7 seconds.

Instead of standing in line for hours to try and book a flight, Kevin's mom could have done it in a matter of minutes online.

Buzz's private things would have been a computer and instead of a Playboy, I have a feeling his bookmarks would've been a little more in the direction of Brazzers.

His parents definitely would've found out because the story would have flooded the internet.

Bonus!
