This has been discussed here and at the DO's before, and the general understanding has been that F is never intentionally overbooked. Here, though, it looks like I've found at least one example where that's not the case. Check this flight out:
[KVS Availability Tool 3.0.2/Lite - Apollo: ITN/US-ARL]
Code:
IAH Houston George Bush Intercnt'l TX US [KIAH]
JFK New York John F Kennedy Int'l NY US [KJFK]

CO is selling 9 seats out of a possible 8 in first on the 737-500. Does anyone else know of flights that are oversold up front?
