flying IAH-CDG-ZRH tomorrow, tried to olci with air france first, they redirected me to delta which redirected me back to air france. does this mean there's a problem, or is that just the deal 'cause of the second leg? (it's cityjet, but with a dl flight number.)

it was one of those cheapies without the fuel surcharge, my original dl metal IAH-ATL-ZRH flight was cancelled so they moved me to af. i'm just hoping this doesn't mean something troublesome.

thoughts?
