Charging for the first or second checked bag improved on-time departure performance for all major airlines--including Southwest Airlines, which does not charge for the first two bags--because it creates savings due to a cultural shift among US passengers to travel with less baggage. | Consequently, the implementation of checked baggage fees resulted in reduced likelihood of on-time departures as long as the carry-on baggage limits were loosely enforced. | The reductions are significant because departure times and mitigating delays are crucial to so many other facets of the business, such as the number of flights airlines can offer and their image among potential customers. Other key findings from the study:
Charging for the first or second checked bag improved on-time departure performance for all major airlines--including Southwest Airlines, which does not charge for the first two bags--because it creates savings due to a cultural shift among US passengers to travel with less baggage. This shift resulted in a lower demand for airport labor-intensive, back-end operations such as baggage handling and security checks, which are shared resources across airlines. | Indeed, checked baggage fees led to more and heavier bags brought as carry-on into the cabin . Consequently, the implementation of checked baggage fees resulted in reduced likelihood of on-time departures as long as the carry-on baggage limits were loosely enforced. The passengers can also check more than two bags, however these extra-bags have always incurred additional fees, thus our discussion reduces to their behavior regarding the first two checked bags. | [5.0, 3.0, 2.0] | Computer_Science | train | 3 | news | http://www.futurity.org/airplanes-baggage-fees-1234212-2/ |

Southwest's "bags fly free" policy is likely not free based on lost opportunity cost, mostly because it could be offering more flights per day with increased boarding times due to charging for checked bags. | Our findings highlight factors, such as the effect of carry-on bags, that need to be incorporated in designing incentive schemes. Our research also sheds some light on the decisions made by a very operationally focused airline.

The reductions are significant because departure times and mitigating delays are crucial to so many other facets of the business, such as the number of flights airlines can offer and their image among potential customers. | Thus, for a company like Southwest Airlines which has a long history of being one of the best in its industry for operational performance and customer satisfaction, the decision of not charging AirTran Airways' passengers for the first two checked bags appears to be in line with their operational strategy. Ultimately, operations managers need to be involved in the discussions about marketing initiatives such as this one to evaluate the operational impact of marketing initiatives. We have an indication that this occurred at some level as our results support the argument that after initially observing little performance decline, the airlines felt the need to shorten their scheduled block times. | [1.0, 1.0, 2.0, 3.0, 2.0] | Computer_Science | train | 1.8 | news | http://www.futurity.org/airplanes-baggage-fees-1234212-2/ |
