Dozens of flights and I've never seen a row's beverages forgotten. I even went back and asked the attendant to check on them and nothing. I really hope it didn't have something to do with the Black mother with her kid in the row. Otherwise it was a typical Southwest flight, rapid boarding, tolerable leg room.

Los Angeles to Chicago Travel Guide

Los Angeles and Chicago are both bustling cities with plenty of things to see and do. While both cities have many similarities, Chicago offers a uniquely Midwestern experience you just can't get on the West Coast. From vibrant neighborhoods to a busy downtown area, Chicago is essentially many smaller towns wrapped up in one large metropolis. You'll find no shortage of things to keep you busy during your stay in Chicago, from improv theaters showcasing up-and-coming comedians to world-class art and history museums. With so much to see and do, you may want to consider staying for a few extra days just to get all of the authentic Chicago experiences checked off of your list.

Los Angeles and Chicago both share a lot in common, but they are defined by their differences. While temperatures in LA are almost always moderate and sunny, Chicago weather is notoriously unpredictable. However, it makes the perfect destination for a summer getaway or a true winter Christmas experience. Chicago is known for its local cuisine, including deep dish pizza and Chicago-style hot dogs, and visits to the local neighborhoods reveal a wide range of international cuisines. Visit Pilsen for its authentic Mexican taquerias or head to Chinatown for its wide range of delicious eateries. The Loop and the surrounding downtown area are home to the Magnificent Mile shopping district, the Art Institute of Chicago, The Goodman Theater and a host of smaller museums and shops. Finish your trip to the Loop with a visit to Millennium Park and a ride on the CTA's "El" elevated train.
