Hi Everyone. I'm on a 4:15 PM flight on Continental from PHX to EWR next Wed.

Last time I flew out of PHX, I flew US Air and waited about an hour and a quarter on the security line at about noontime.

Now, I know that US Air flies from Terminal 4 which is much much bigger than Terminal 2, where CO flies from. I'm also wondering if that long wait might have been a fluke.

I guess my question is should I expect to wait that long for a CO flight at PHX? Normally, I'd feel comfortable returning my rental car about 100-120 minutes before takeoff. But if the security lines are going to be 75 minutes, I should probably return the rental 2.5 hours before takeoff.

Anyone have any suggestion for when to arrive to return the rental?

Thanks.
