The 10 US Airlines Total Net Deferred Income Tax Liabilities Were $1.104 Bil at December 31, 2016, But the 4Q Regular After-Tax Earnings Increase Due to the Trump Tax Bill Will Be Sustantially Higher Than 43% of $1.104 Bil Due To Both a Large Deferred Income Tax Asset Related To Pensions & Other Postretirement Benefits of $10.646 Bil and a High Percentage of This Amount Being Charged To Other Comprehensive Income X 43% and Thus the Amount of Increase in 4Q Regular Net Income Will Be Substantially Higher Than 43% of $1.104 Bil ...................................................................................... Using Specifics, Assuming 80% of the $10.646 Bil of Total Deferred Income Tax Assets Re Pensions and Other Postretirement Benefits X 43% is Charged To Other Comprehensive Income or $8.517 Bil X 43%, The Regular Net Income Increase Due to the Trump Tax Bill is 43% 0f $9.621 Bil, a Huge 8.7 Times the Increase in the Net Deferred Income Tax Liability of $1.104 Bil X 43% ...................................................................................... If Instead 90% is Assumed, the Increase in Regular 4Q Earnings Due to the Trump Tax Bill is a Higher $10.685 Bil X 43% ...................................................................................... Moral of Story: The Impact of the Trump Tax Bill on 4Q US Corp Earnings is Monumentally Huge, Highly Variable and Extremely Complicated and Extremely Time Consuming: Nearly Every US Citizen Will Be Shocked By The Magnitude of These US Corp 4Q Earnings Changes Going in Both Directions, But Clearly Mostly Going Up, Due to the Trump Tax Bill and a Very High Percentage of the Up Earnings is Due to the US Government's Massive Debt Forgiveness Granted to US Corps of More Than $1 Trillion in Total

From a review of income tax footnotes in SEC filings, below here are the 10 US Airline Companies Net Deferred Income Tax Assets (Liabilities) and the Deferred Income Tax Assets Re Their Pension/Other Postretirement Benefits embedded in the Net Deferred Income Tax Assets (Liabilities), both at Dec 31, 2016.

Also below is the estimated 4Q journal entry using the December 31, 2016 amounts and also assuming that 80% (it's probably higher) of the Deferred Income Tax Asset Re Their Pension/Other Postretirement Benefits Total is related to Other Comprehensive Income.  This computation also assumes that the Trump Tax Bill does not include a one year delay, which makes little sense and dramatically increases the time necessary for US Companies to make this very involved computation, which must be audited by their external CPA firms.
