Comcast acquired European media firm Sky for 30.2 billion British pounds in October 2018 after winning a bidding war against 21st Century Fox. Comcast revenue increased more than 11 percent in 2018 to $94.5 billion, a figure that includes Sky revenue after the October acquisition. Comcast at the end of 2018 had 184,000 full- and part-time employees. In 2019, Comcast will consider if and how Sky could be integrated into its travel operations. For now, some Comcast divisions mandate air and hotel booking through agency or online booking channels. Comcast’s NBCUniversal subsidiary expects its air travelers to take the lowest priced logical nonstop flight offered, whenever possible, on a preferred carrier, and requires travelers to stay in specific designated hotels when in major cities. For air travel, coach class is required for domestic U.S. travel, but some travelers on international flights longer than six hours are eligible to upgrade one class of service: to premium economy if available, otherwise to business class.
