According to NBC News, the shutdown won’t affect your flights at all:
As far as getting a passport or dropping by an embassy goes, ABC News says:
INTERNATIONAL TRAVEL
I’ve seen some editorials panicked about the possibility of a half a million passport applications going unread, but I’m fairly confident the fees would keep it afloat.
I also doubt anything would change with air travel. During sequestration talks, I was on a flight that got affected by the flight controllers making a point. Congress flies too, and they quickly exempted air travel from being affected by the sequester. For once, Congress’ self-interest helps us 😉
If you were taking a vacation-vacation, look at what you were planning to do. National Parks, Visitor Centers and National Museums are on the chopping block, so if those were in your plans, try finding alternatives nearby just in case. This includes things like Alcatraz and the Statue of Liberty.
Amusingly, NBC News reports the Washington Monument will be closed if there is a government shutdown–The Washingon Monument has been closed since 2011 due to an earthquake.
But maybe they won’t light up the scaffolding so pretty at night anymore.
There is already a subtle impact that has occurred even if the govt is not shut-down. I’m a fed who hasn’t had a raise in three years, yet all of my costs-of-living (e.g., insurance, tuition) have increased each year. Feds are repeatedly depicted as being nothing more than a bargaining chip whose salaries and livelihood are relevant only as leverage for political parties. Yet we are people who are worrying about how to pay for our families’ needs. As a result, my travel has declined measurably — and will continue to do so until I know I have a paycheck coming to me. Multiply my situation by some 800,000 families–and yes, there is an impact on air travel and the associated hotel/rental car industries. I won’t even talk about my morale these days.
