Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsThe travel industry continues to be adversely affected by the global health crisis due to the outbreak of the coronavirus (COVID-19) in January 2020, especially as it relates to air travel to and from Asia. We expect a material impact to our consolidated financial results in the first quarter of 2020. Given the uncertainties surrounding the duration of the outbreak and its impact on global travel, we cannot reasonably estimate the related financial impact to our full-year 2020 financial results; however, we expect the impact will be material.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
