In the wake of the Boston Marathon tragedy that killed three and left a reported 140 injured, the people of Boston are coming together to help in anyway they can and that includes the aviation industry, who have announced that "most carriers are waiving change fees for customers scheduled to fly there during the next few days," according to USA Today.

Unlike in other cases were "most" means, not the major airlines, this includes major airlines.

"All of the nation's biggest airlines have instituted flexible rebooking policies, including American, Delta, Southwest, United and US Airways. Also waiving fees for Boston customers is JetBlue, the busiest carrier at Logan airport," stated USA Today.

Though the actual rebooking procedures and what fees are waived varies by airline, in general terms, according to USA Today, "the waivers allow fliers to make one change to their itinerary without paying the customary change fees or resulting fare differences. Most airlines' policies cover customers who had been ticketed to fly through Boston between Monday and Wednesday (April 15-17)."

"Boston Logan International Airport remains open, connecting Massachusetts and New England to the world," Thomas Glynn, CEO of the Massport agency that operates Logan Airport, said in a Tuesday morning statement. "There is heightened security on roadways, in terminals, and on the airfield."

"Yesterday, the Federal Aviation Administration changed the runway configuration in use at the airport and in doing so issued a ground stop-a common occurrence to slow traffic headed to an airport by keeping planes on the ground," Glynn said in the statement. "Planes continued to depart Logan and flights in the air landed at Logan as scheduled. The ground stop lasted for 20 minutes and the airport remained open and operating throughout that time."

Glynn also made clear that the safety and security of the people is the top priority.
