Two passengers on an American Airlines flight from Boston were escorted off the plane because they were speaking Arabic.
According to myfoxboston.com, the two Arabic men were not sitting together on the flight to Chicago and were removed from the plane as there were worried marathon runners on board.
No other details or information as to whether the men were later allowed to fly were made available.
Meanwhile, a US Airways flight from Philadelphia was evacuated when it landed in Boston after a suspicious bag was found.
The Transportation Security Administration (TSA) later said in a statement: "Out of an abundance of caution, a checked bag on board US Air #1716 (PHL-BOS) was re-screened at Logan International Airport upon landing after baggage handlers at PHL noted concern.
"The flight landed safely at BOS and passengers were deplaned and bused to their gate. TSA and the Massachusetts State Police responded.
"While properly screened by TSA at San Francisco International Airport (SFO), the bag was re-screened by local EOD at BOS as a precaution and has been cleared."
The police said the incident was not related to Monday's bombings in the city.
In New York, a terminal at LaGuardia Airport was evacuated after a suspicious package was discovered in a shopping area. The all-clear was given 15 minutes later and passengers were allowed back into the terminal after about 45 minutes.
CNBC reported that the Port Authority Public Affairs confirmed the suspicious package turned out to be a "lighting ballast with wires sticking out".
On Monday, two bombs exploded in the crowded streets of Boston at the finish line of the Boston Marathon. Three people died and more than 130 were injured.
