An "unusual odor" on a JetBlue flight delayed a Dominican Republic getaway for a bunch of cold Northeasterners.

The Federal Aviation Administration (FAA) will investigate after a JetBlue flight en route to Punta Cana from Boston's Logan Airport turned around this weekend after a strange odor was detected on board, an FAA representative told Travel and Leisure.

JetBlue Flight 1095 returned to Logan Airport in Boston after "an unusual odor" on the A320 aircraft left "customers and crew members feeling unwell" — with some asking for medical attention, according to a statement from the company published in the Boston Globe. The airplane was in the air for just over an hour and underwent an inspection upon landing at 6:24 p.m. Saturday, according to JetBlue's FlightAware tracker.

It is unclear what caused the odor. According to JetBlue's FlightAware tracker, it appears the flight had been delayed for six hours on Saturday already before the issue arose in the air.

Representatives from JetBlue did not respond to a request for comment from Travel and Leisure.

The issue of a strange odor on board is nothing new for JetBlue. On an August flight from Boston to Charleston, an odor caused by nail polish remover sent two crew members to the hospital. Several other JetBlue flights — on Airbus A320 planes in particular — have been diverted as a result of mysterious fumes in recent months, according to CBS News.

Boston was one of the East Coast cities most heavily hit by Winter Storm Grayson this week as it tore through a number of U.S. states. Logan Airport had very low visibility Thursday as the storm caused more than 15 inches to fall in the city, canceling school for many students and leaving some cars in a Boston suburb trapped in frozen ice.
