As the nation prepares to mark the fifth anniversary of the September 11th attacks, it is not hard to find changes that have occurred since that fateful day.
Whether it's by train or plane, September 11, 2001 changed the way we live, and the way we travel.
"It's harder to travel today," said Dr. Peter Tarlow, President of Tourism & More Consulting.
Tarlow is an expert on the impact of terrorism on the tourism industry, and advises the Department of Interior on tourism security.
He says while some areas of tourism have recovered since September 11th, others still need improvement.
"I don't think airline travel will go back to the ease of pre-nine-eleven," said Tarlow.
The airline industry lost $5 billion from Sept. 11 to Sept. 30 and requested $24 billion in aid from the federal government.
Today, diverted flights and tougher screening procedures are daily reminders that we live and travel in a very different world.
According to Tarlow, "the big issue isn't can we get rid of the hassles? It's can we move from reactive security to proactive security?"
Tarlow says the hassles of traveling are likely here to stay. But incentives and good customer service should encourage Americans to keep flying the friendly skies.
"You are not only secure by your physical security, but if you destroy the economy of a country or a community, to a great extent, you have hurt its security tremendously," said Tarlow.
According to a new CBS News poll, 68 percent of Americans understand they will have to trade freedom for security.
