A benefit of the Citi Prestige card is a $100 credit towards the Global Entry application when you pay the application with your card. Since the application is $100 and Citi automatically credits your account, I thought I might as well make use of it. This is my experience with the Global Entry application process.
What is Global Entry and why would I want it?
Global Entry is a program for US citizens (and a handful of other folks) that allows you expedited customs when returning to the USA. Once approved, you are also enrolled in TSA Pre√ which allows you to move through TSA checkpoints in airports quicker (and you get to keep your shoes and belt on and your liquids in your carry on). It is good for 5 years.
