Dear Mr. Gretch:

United 1 holds an operating designation to provide year

- round scheduled service between

Chicago and San Jose del Cabo , Mexico

. 2 United is writing to advise the Department that it has

decided to serve this route on a seasonal, rather than a year

- round, basis going forward , and

requests that the Department convert United’s designation accordingly

. United understands that

of the three U.S. carriers providing Chicago

- San Jose del Cabo service

, only United ’s

designation provides for year

- roun d operations

. 3 G ranting United’s request would thus provide

it with the s ame flexibility that United’s competitors have with respect to this route

. 4

In the event that the Dep artment decide s not to grant United’s request to convert its

Chicago

- San Jose del Cabo designation to seasonal service, United requests a temporary waiver

of the 90

- day dormancy condition
