Woman in headscarf denied only fun part of air travel.

Excuse me, ma'am, can I see your Diet Coke owner's permit? (via Facebook)

Complimentary beverages are all we, as airplane passengers, have left. It's our one moment to make a choice, get something for free, and enjoy ourselves for two to three minutes before returning to checking to see if the in-flight wifi suddenly became free.

And now that small joy has been denied a Muslim chaplain who is claiming she was discriminated against because of her religion.

31-year-old Tahera Ahmad is a chaplain and director of interfaith engagement at Northwestern University. On Friday, she was traveling from Chicago to Washington for a conference bringing together Israeli and Palestinian youth. Ahmad requested an unopened Diet Coke for hygienic reasons and was told that wasn't allowed because it might be used "as a weapon."
