If you're going to be stuck traveling, you might as well get smarter, the IPA way. Here are some podcast episodes we in the family liked:

 

Note: These tend to be about social sciences and development, if you want more variety of episodes others like, see New York Public Radio staff picks of 2014,  earbud.fm, and the audio signal newsletter.

• Freakonomics' episode "Is Migration a Human Right?" interviews several economists and others to smartly delve into the different arguments on both sides.
• Tyler Cowen's interview with University of Chicago Economist Luigi Zingales covers a lot of interesting topics, including why he's upset the world's leading coffee company isn't Italian.
• The Financial Times Alphachatterbox podcast has a longform interview with Esther Duflo covering the basics on econ of poverty, microcredit, the ultrapoor graduation pilots, and ethics of aid.
• Unfortunately timely is the Radiolab episode on how people mis-remember the Kenya Westgate attacks, even people who were there. 
• The Rationally Speaking podcast has very good social science guests, worth browsing, but political scientists Andrew Gelman explains why people vote the way they do, and Phil Tetlock on "Superforecasting: The Art and Science of Prediction."
• Freakonomics had two episodes on Preventing Crime for Pennies on the Dollar, featuring IPA and J-PAL RCTs on crime prevention. Part one, part two.
• Iran is the only country with a market for kidney buyers and sellers, Econ Talk spoke with the New York Times Tina Rosenberg in depth, covering issues from economics of markets when lives are at stake to the ethics. It was nice to see two very smart people from different perspectives really wrestle with the issues thoughtfully.  A nice companion is Planet Money's "Your Organs Please" on how people are nudged to donate organs in the U.S., where we can't use money.
• WNYC's Only Human podcast is doing a series of short episodes on how to be a better listener, with advice and exercises from experts in different areas. (Economists of course don't need this.)
• Econ Talk with economist David Skarbek on how prison gangs create their own political institutions was fascinating.
• In the course of Planet Money telling the story of the Onion King, they end up teaching us why futures are a really important tool for farmers.
• Here the Planet Money folks look into an ISIS municipal budget, and discover among other things, they issue permits for and tax looting.
• Two pocasts about development where you're guaranteed all espisodes are good are Tiny Spark and Humanosphere, but some interesting ones:
  • Tiny Spark: Kentaro Toyama on why we shouldn't be looking to technology for answers in development, and in a crisis do medical volunteers help or hurt?
  • Humanosphere: Michael Clemens mythbusting on the economics of (im)migation, and collaboration and optimism in the hunt for an AIDS vaccine.
