Yes. Most (or almost) most of the commercial flight time is spent at not cruising altitude and speed - I've taken longer to get to the airport than the flight, and then once you're there there's security (although Burbank is usually a breeze), passenger loading, taxiing, take-off and climb... Then just enough time for a drink service and you head back down, to do it all over again in reverse.
