Back in the good ol’days — the ’90s — John Travolta would love to get off the topic of “Michael,” “Pulp Fiction” or “Get Shorty” in interviews with film journalists like me and regale us with how utterly besotted he had been with his first flying experience, how that drove his passion for piloting and buying planes and airfield-adjacent luxury houses.

He didn’t even seem to mind having to move house when this or that development balked at him flying his Boeing 707 out of there on the way to locations.

Travolta would tell any journalist who asked that he was writing a kid-friendly book, “Propeller: One Way Night Coach,” based on his first flights as a child in old propeller driven airliners — cheap red-eye overnight treks with too many connections for your average jet age traveller to tolerate.

I remember picking up the book when it came out later in the ’90s — at an airport gift shop — and thinking “Well, that’s as cute as I figured.”

And now, decades later and trapped in the B-movie hell of his post “Gotti” career, Travolta’s turned that cute book into the most delightful, fanciful and colorful bon bon of a movie.

“One Way Night Coach” is a child’s fantasy of flight and flying the way it used to be — with pristine, uncrowded, futuristic airports, an early ’60s era of jets and prop planes with over-uniformed stewardesses in white gloves, the days “Back before every Joe Sweatsock could wedge himself behind a lunch tray and jet off to Raleigh-Durham,” as Sideshow Bob memorably sneered on “The Simpsons’.”

It’s a fictionalized account of Travolta’s childhood about an only child (at least two Travolta siblings have bit parts in this movie) of a never-made-it/never-will actress/single-mom (Kelly Eviston-Quinnett) who indulges her aviation-obsessed eight-year-old with a cheap cross-country overnight flight.

Little Jeff (Clark Shotwell) will revel in almost every Idlewild to Pittsburgh to Dayton to Chicago to Kansas City to Denver and Los Angeles minute. He strolls into the cockpit to meet pilots, charms the stewardesses and checks out the sleeping bunks on the TWA Lockheed Super Constellation, loving even the delays if not the Chicken Cordon Bleu he’s offered on legs of the journey that offer a meal.

And as he’s an observant child, he comments (Travolta narrates) on his 50ish mother’s vamping and posing, her choice of cigarettes (Newports) and drinks, the solo traveling men whose attention she pursues and earns.

“I was her best audience,” adult Jeff remembers of the mother who’d read him plays as bedtime stories and delusionally hopes that this trip to Los Angeles might be her “big break” even though she’s pushing 50.

“Hollywood called,” she’d explain about their overnight cheap flight arrangements to ticket agents and crew. “They told me to take the next flight!”

At every turn, Jeff meets or sees kindness — stewardesses who indulge his many questions and bump them up to first class on the mostly-empty planes, a captain who fixes his toy model of a Constellation, a mentally ill flyer who flips out but is calmed by a flight attendant who isn’t overworked and frazzled in jet-powered tin-can jammed with Joe and Jane Sweatsocks who think nothing of traveling in their pajamas.

Normally, I cringe at pictures this reliant on voice-over narration. I recoil from stars who populate their picture with Sandler etc. offspring. But “Propeller” is unfailingly sweet and never cloying.

Sure, it’s fictionalized. But if you’ve followed Travolta’s life and career, a lot of him is in this — his raptoruous engagement with flying, an indulged child who developed a taste for fine food and creature comforts, a mother who was his guiding star as an actor.

I get why there are less adoring reviews than mine floating around “Propeller.” It’s unfailingly sweet. Mom’s man-hunting is seriously dated. This TWA tale is decorated with Gershwin’s majestic “Rhapsody in Blue” — United Airlines’ signature tune. And Travolta’s been around long enough for recent generations to come up and not feel a connection to the “Saturday Night Fever/Get Shorty” star whose career has fallen off and life has been visited by too much tragedy.

But I’d hate to be seated next to anybody who doesn’t appreciate this adorable, pristine and nearly perfect aviation fantasy on any flight, much less an overnight one.
