With the load factor on U.S. airlines at a record, passengers are facing higher prices for fewer seats for summer travel.
The load factor has climbed steadily over the past decade—to 83 percent in 2011.
Through the first 10 months of 2012, the load factor for domestic flights was 83.6 percent.
Ten years ago, the load factor—the percentage of seats actually occupied—was generally in the mid-70 percentages.
Many schemes are employed for improving the load factor, or, in other words, to encourage a long use of central station product.
In practice, the load factor for electric crane motors varies from 1⁄3 to 1⁄6.
This question of load factor is by all means the most important one in central station economy.
