I was supprized to get the e-mail notification of an upgrade for a trip I was not planning. I called continental since it was a city pair that I do occaisionaly fly and they informed me that it was made by our corporate travel agency (I book on the internet for the extra 1000 miles) I have a co-worker on the opposite coast with the same name - Last week he traveled for the first time and the corporate travel agency booked his ticket under my profile.

In sent the other John Smith an e-mail letting him know he had a suprise comming when he gets to the airport.

Since Mr. Smith and I have the same first and last name an there is no middle initial in my FF account he had no problem receiving the upgrade and I received the miles.

The travel agency figured out what they did wrong and set up a new profile for the other Mr. Smith

The other Mr. Smith is flying again next week and has asked if he can use my FF number again to get the upgrade, and I receive the miles.

What are my risks,the first one was an error by a third party. However he now has my FF # since it prints on the boarding pass
