British Airways First Class Lounge Chicago O'hare ORD Terminal 5

I am an American Airlines Executive Platinum Flyer, which means I have access to all One World Lounges regardless of what One World airline or what class I am flying.  I have Priority Pass access as well, but that was not tested at this lounge.

From the One World Website:

"When your top tier status is equivalent to oneworld Emerald, you are entitled to the following oneworld benefits, no matter which oneworld airline or cabin class you are flying:
Access to First Class or Business Class priority check-in
Priority boarding
Access to preferred or pre-reserved seating when offered by the airline operating the flight
Priority standby and waitlisting (where offered)
Access to more than 600 airport lounges (with one guest) when traveling internationally, including premium First Class, Business Class and frequent flyer lounges, regardless of the class of service flown that day."

We were flying Royal Jordanian Crown Class to Amman and had about 45 minutes until boarding.  The closest and best lounge was British Airways First Class Lounge in Terminal 5 at ORD.

After a long day of traveling, when I approached the hostess to check in, I was told that the Royal Jordanian (Air France) lounge was farther down the terminal.  I said that I had One World Emerald status and I would prefer this lounge.  She continued to argue with me that we did not have access.

Disappointing!
Again I was told I couldn’t enter despite emerald one world status.  She argued with me and kept directing me to Air France lounge.  Then she said that she was not going to argue with me anymore, and she was going to grant us entry...

“You’re lucky it’s a late night for us...”

Liquor excellent like I would expect from the Brits.

Bathrooms small and single.
No shower.

Elemis products.

Food looked old.

Snacks average.  Oreos? Really?

WiFi fast
Chairs uncomfortable.

Power outlets plentiful enough with usb and plugins
