It's not exactly a jumbo jet, but if you fly Cape Air around Massachusetts, to/from Martha's Vineyard and Nantucket for example, you get a great view through the windshield of their Cessna 402s.

(It can be a bit worrisome, though. When you see nothing but cloud out a side window, you may know intellectually that the pilots can't see anything either, but it doesn't really hit you. When you're looking out the same windshield and know the pilot sees nothing but the same clouds you do, it has much more gut impact. Knowing that the pilot's instruments are up to the tasks of keeping away from other planes and finding the airport doesn't change that impact much.)
