Catch flights and feelings.

A bold plane passenger has gone viral on TikTok after revealing she put her phone number on a napkin and handed it to a “cute” fellow flier on board a recent ride — before he sparked up conversation.

The flirty flier, known only as Natalie, made users swoon as she relayed the romantic tale in a clip that has clocked up more than 2.9 million views in 24 hours.

The viral video shows the San Diego native sitting on board a Southwest flight after noticing the hunky man sitting in the row ahead of her.

“Really cute guy sitting in front of me on my flight,” Natalie captioned. “Decided to shoot my shot.”

The intrepid traveler subsequently shared a photo of a note she scribbled down on a napkin, which read: “If you’re single/ interested, text me sometime.”

She added a smiley face and her phone number before brazenly handing it to the man.

Remarkably, Natalie’s potential paramour turned around and introduced himself to her. She was left “freaking out” after the brief exchange.

Later, Natalie’s phone pinged with a text message from the man, who wrote: “Hey Natalie, nice to meet you. Yes, single and interested.”

The mile-high hijinks sent viewers into a frenzy, with many claiming they were eager to hear more of the story.

“Where do we subscribe to relationship updates?” one lovelorn follower commented beneath the video.

Another wrote: “As a Southwest flight attendant, I’m fully invested.”

The flight flirtation even prompted the official Southwest Airlines TikTok account to respond with a comment that read: “As the love airline, we’re now invested!”

Natalie subsequently uploaded a second video dishing further details of her text message exchange with the anonymous hunk.

“I’m free tomorrow and Monday night,” the man wrote in a message which was screenshot and shared by Natalie. “Down for a date night? There’s a couple of places I wanted to check out.”

The TikToker revealed she would update followers after the date had taken place.

The Post has contacted Natalie for further information.

In the meantime, the bold flier told her followers that the sky-high story was proof that people should go after what they want.

“Thanks for the support!” she wrote. “I hope this encourages some people!”
