Tried to book a short trip to Chicago using AC's current 20% off promo code. T&Cs note travel dates must fall between June and December. Trip dates are in August. Yet AC's website consistently tells me the dates fall outside of the range for the promo code.

I tried multiple date combinations - including some in July, and various days of the week - and got the same result. Destination city is one of the "selected" US destinations identified in T&Cs. What's the sense in having these idiot promotions if the website won't even recognise them?

Very disappointed in AC's feeble IT ... again.
