WINDSOR LOCKS, CT (WFSB) - The president has grounded all 737 Max 8 and 9 planes.
The order comes after two of the planes crashed.
Travelers at Bradley International Airport in Windsor Locks said they're paying attention to the situation.
The U.S. joined many other countries that have grounded the planes, including Canada, China and all of Europe.
Boeing's CEO ensured people that the 737 Max planes were safe but supported the decision to ground all of them out of an abundance of caution.
Sunday, a Max 8 plane crashed in Ethiopia, killing 150 people, including 8 Americans.
The crash came 5 months after a crash involving the same kind of jet came down in Indonesia.
Earlier this week, several Congressional leaders, including Sen. Richard Blumenthal, called for the Federal Aviation Administration to ground the aircrafts.
President Donald Trump called the decision necessary to protect people and for peace of mind.
Travelers at Bradley told Channel 3 that they're on board with the decision.
"If there's any fear of malfunction or a problem, you got to do safety first," said Andres Carro, a passenger. "I don't care how late I'm going to be as long as I get there."
"One hundred percent a great idea, I believe," said Robin Grubb, also a passenger. "I would rather be safe than sorry."
Bradley said 737 Max 8 or 9 planes do not regularly fly out of the airport because of the weather or maintenance. However, they can end up there.
Thursday, the black box from the Ethiopia plane will arrive in Paris for analysis, which may provide some clues as to what happened to it.
If you're traveling in the near future, AAA says don't panic.
"The advice is to go onto the airline's website, take a look at what their terms and conditions as far as the change goes," said Suzanne Aresco, AAA Spokeswoman.
Aresco said the airlines are working swiftly to make any necessary changes and helping travelers as best they can once they are contacted, but also not to rely on them to contact you.
"If you haven't been paying attention to this situation and you haven't check what your flights are, I do suggest that you take a moment to look and see if your plane was affected in the situation," Aresco said.
Although airlines are offering free flight changes, travelers should be aware of other expenses they may incur.
"There could be additional expenses on hotel charges. Say all of a sudden your flight is going to be the day after you were initially flying and you haven't come home, you need to take a look and see what these additional expenses could be," said Aresco.
With the headache of grounded flights, there is a small silver lining.
"We have not see that a family has lost their dream vacation to say Disney or something along that lines. A cruise hasn't been interrupted," said Aresco.
Aresco said there could be a finite amount of time to make changes to your flights, so if you need to make those changes, she advises to do it sooner rather than later.
