There is no sign of Flight 370, however, new clues are emerging.
The Malaysian military says the missing jet changed course mid-air, which only adds to the mystery.
As the investigation continues, a valid question for travelers lingers: Will the stolen passports used by two of those passengers change security policies at airports?
A senior Malaysian air force official said the Boeing 777 was hundreds of miles off course, traveling in the opposite direction from its original destination.
There are still questions about the two men on board who had stolen passports.
Rice University professor Chris Bronk said that regardless of what caused the plane to vanish, this whole thing has shed light on security flaws with passports at airports.
"What we have is a failure on the back-end to support all that infrastructure so basically the computing to assure you're who you are and someone else isn't being used," said Bronk.
Interpol has a database of stolen and lost passports, but the issue is that only a few countries, including the United States, actually use it on a regular basis.
"I would imagine that the wealthier countries that don't do this will start taking a look at doing it because it just makes sense," Bronk said.
Local experts say if there are changes with passport security, don't expect them to happen anytime soon.
A former U.S. aviation investigator said that if, in fact the plane was going another direction than what it was supposed to, that would call into question whether someone in the cockpit might have deliberately steered the plane away from its intended destination.
