Her life is up in the air -- literally … Laine Turner lives a little life. Between her job as an anonymous administrative assistant and her small circle of friends, Laine only truly feels like herself when she travels to England on her annual vacation to reunite with her exuberant extended family -- and her longtime boy-next-door crush, Jonah (aka her grandma's neighbor). But this year, Laine's favorite cousin, Lulu, has a big announcement: she's engaged to Jonah … and the couple wants Laine to be the maid of honor and best mate at their wedding. How can Laine say no? This turns Laine into a frequent flier, commuting from NYC to London on a semi-regular basis to help with wedding prep -- and sadly, to check in on her ailing grandmother. Luckily for Laine, she often has a handsome seatmate: Dr. Ridley Aronsen, who travels just as regularly as Laine for his work. The two quickly realize their chemistry and plan their commutes so they can travel together. But Ridley hasn't told Laine that he's a widower and a single father now -- opening up to love again is harder than he realizes. A steamy layover in Amsterdam convinces him otherwise, especially once Laine invites him to be her plus-one for the wedding.
