I'm in the exact same situation too ! No arrival scan anywhere after it departed from Sharjah at 10:01. I called Apple today and the person on the phone told me that the delivery was planned tomorrow (I'm in France). After all, the mail I got when the MBA shipped stated "delivery on 07/26". Did she just read that or did she have some information about the actual tracking ? Guess I'll know tomorrow. I find it weird that UPS doesn't show any estimated date on their website since after the parcel got delayed.
