American and Hawaiian weigh in on China setting off clash

American Airlines and Hawaiian Airlines are weighing in against different aspects of Delta Air Lines and United Airlines applications for new service to China. American objects to Delta's request for 7 weekly frequencies for a new daily flight to Shanghai Pudong from Minneapolis/St Paul, the airline says in a filing with the US DoT. It argues that the regulator cannot grant the frequencies, and a similar one by United, without denying its own request for a dormancy waiver. Hawaiian, on the other hand, objects to both Delta and United's request for a start-up date in 2020 for their proposed new routes to China, in a separate filing on the same day. Granting the requests would be a tacit endorsement of the airlines' "warehousing" the frequencies for nearly 2 years, it argues. <br/>
