Ben Affleck and Jennifer Garner aren't going to let a pesky thing like divorce get in the way of a family vacation.

The 43-year-old actor and his estranged wife left Los Angeles on Friday for a vacation in Montana, where they own a condo.

The couple, who announced their separation in June 2015, were seen boarding a private plane to Yellowstone National Park, a source told ET.

Two of their children, 7-year-old daughter Seraphina and 3-year-old son Samuel, accompanied them, but their oldest daughter, 10-year-old Violet, reportedly did not travel with the family.

The vacation doesn't signal a romantic reconciliation, however, but rather is likely taking place around Valentine's weekend due to their children's schedules. Many California schools take a break around in mid-February for Ski Week.

Since their split, Affleck and Garner, 43, have appeared determined to keep things on friendly terms. They have been photographed grocery shopping, enjoying dinner out at Nobu, and sources tell ET they are still living together.

The divorce comes after 10 years of marriage for the A-list couple. Affleck was rumored to have cheated on Garner with their former nanny Christine Ouzounian, a claim Affleck’s camp has vehemently denied.

"The story is complete garbage and full of lies," Affleck's rep told ET at the time, adding that "all allegations of a romantic relationship are baseless and untrue."
