Amid the unpleasantness, there are a few bright spots where airlines inject a bit of humanity back into our journey. [...] with a record 222 million passengers expected to fly on U.S. airlines this summer, we could use any little bit of sympathy. [...] recently, only Alaska Airlines thought the extra money should guarantee passengers something in return. Since 2010, the airline has promised that suitcases will be on the carousel within 20 minutes of the plane arriving at the gate. Speaking of luggage, you can skip the baggage carousel and have your bags delivered straight to your home, office, hotel or any other location within 40 miles of the airport. The latest innovation: the ability to stream movies and TV shows directly to our tablets and smartphones. Passengers sit waiting for flight attendants to roll the cart down the aisle and then order a beverage or buy a snack knowing that they are unlikely to see the cart for the duration of the trip. Throughout the flight, passengers can order cookies, chicken sandwiches, margaritas and more on touchscreens in front of them. [...] this service keeps the overhead bins less crowded and prevents passengers from forgetting jackets in their tropical hotel room closets.
