You should write a letter with your details to TWA's customer service address. They will perhaps send you a $100 travel voucher,l an upgrade, or mileage. You might tell them which you would prefer. They may look into why your DCA-JFK was late, and if due to weather, they may be less likely to compensate you with anything saying the situation was an act of nature. You might also try calling TWA customer service, that might be quicker. Unfortunately, I have never flown TWA<SODON"THAVEnumber/email address. If you call the 800-221-2000 they should be able to find it, or check the web site.
