Usually, the problems that annoy air travelers are not with the planes themselves, but with the airports. Simply put, many municipal airports were designed years ago, when air traffic was considerably less. They cannot cope with today’s heavy around-the-clock volume. Also, today’s planes are much faster and bigger than was the case years ago. Modern planes need more room to land and take off. Again, many older airports are just not able to accommodate these large planes. Because of scheduling problems and congestion, not to mention hazardous weather conditions, many flights take off late, arrive late or both. This is a particular problem in the colder states during the winter months. Heavy rain, snow, fog, or worst of all, ice and sleet, can all lead to long delays, flight cancellations, or even the closing of an entire airport. When these inevitable problems occur, there is not much the airlines can do other than house and feed travelers while they wait for their flights. However, free meals and hotel rooms rarely satisfy travelers—they just want to get where they are going when they are supposed to get there.
