Capital One Venture Vs. Venture X: Should You Upgrade?

I have had a Venture card for years. As a matter of fact, I have been "grandfathered" in so that I have no annual fee. In that instance, my comparison is $0 annual fee for Venture vs $395 for upgrading. What would you do in this instance?

Odd quirk I was trying to book an AA flight for one of my sales reps with the $300 credit and it would not ticket. I went thru multiple tiers of support and was on the phone for over an hour. In the end AA’s CC processor rejected the virtual card that C1 uses for ticketing so I had to book elsewhere. It was very strange as it was just a standard domestic flight nothing crazy. Beware if you frequently fly AA

Please do NOT consider "lounge access" to the Capital One lounges to be a perk, if the one in DFW's Terminal D is anything to go by. DFW is my home airport, and I fly out of it every two weeks, and access to the lounge is near impossible as it is ALWAYS full. You get your name on a waiting list and they'll text you if/when there is space availability. It'll likely be time to board your flight when that happens! DFW has numerous good places for food, and I would now prefer to spend my time at any number of those places than to waste my time waiting to enter this lounge. It's just not worth my time.
