[Sorry for the thread bump, but figured it'd be good to keep baggage storage questions together.]

We'll be flying US - IST - South Africa this November, and actually stopping and spending a few days in IST on the return trip. It's likely to be quite a bit colder in IST than SA, so we had this crazy idea of leaving a bag with warmer clothes at the left luggage in IST during transit on the outbound, and then picking it up when we arrive on the return. This raises a couple questions:

• Can we leave a bag for ~10 days? If it's still around 53 lira per day, as mentioned above, that wouldn't be an unreasonable charge even for that long.
• Is there even a way to access the left luggage office if we're just transiting? The previous post says that it's past customs, which seems to rule that out, but wanted to check if there were other options.

Thanks!
