It was a record year for Boston's Logan International Airport in 2018. The New England hub handled more than 40 million passengers last year. That's the first time in the airport's history that such a high volume of passenger traffic has been seen. Officials at the airport are now looking at expansion options.

Logan's very busy 2018 placed the airport ahead of hubs like Philadelphia and Minneapolis-St. Paul. Much of the increase seen by Logan in 2018 was thanks to Delta and JetBlue. This has been the case consistently since 2010. Of course, all of the other carriers that fly out of the Boston hub contributed to a record-breaking 2018. Passenger departures at Logan grew by 41 percent during the period between 2010 and 2017. Only Seattle-Tacoma International Airport and Fort Lauderdale International Airport saw more growth during the same period.

Most of the growth happening at Logan is due to international traffic. More than 18 percent of all traffic at the airport in 2018 was international. International traffic accounted for just 13 percent of all traffic at Logan in 2010. What's more, Logan grew from offering flights to 30 international destinations in 2010 to offering flights to 55 international destinations in 2018. The new additions include places like Tokyo, Hong Kong, Dubai, São Paulo and Morocco.

What's in store for the future at Logan? We know that Terminal E will be getting an additional 400,000 square feet of space. Terminal B and Terminal C will be getting makeovers that will allow for better flow. In addition, $1.5 billion will be spent to build an automatic people mover that will bring passengers to terminals, rental car areas and a Blue Line station.
