This may just be me having a run of vaguely poor luck.

When I book a rental in the US via the UK site, there is no ability to add Sirius to the rental. The UK site is generally quite a bit cheaper.

On arrival, I ask to add Sirius. No big deal, you may think.

So far this year, I'm 0-6 at my usual destination for the radio activating without a call to ask the signal be sent again. Sometimes it works, sometimes not.

PIT, which I fly into every so often, seems particularly difficult. During a recent rental -

- Asked at the counter. Radio not active when I set off.

- Called on the road. Phone agent said car doesn't have Sirius. Told her I was looking at the preview channel. It then bizarrely switched to claims Avis didn't pay the subscription. When I returned the car, the agent said they had no record of anyone ever trying to activate the radio.

I know it's minor stuff in the grand scheme of things, but does anyone else have this level of failure getting Sirius? I wish it was easy as calling ahead, but UK call centre refers to the US one and vice versa.
