The unusual love note was found by staff cleaning the plane.

A message written on an airplane sick bag has gone viral.

The note, which was posted on Reddit, was penned by an American woman named Andrea.

During a flight last year, the nervous 21 year old revealed on a sick bag that she was travelling to tell her best friend that she was in love with him.

She detailed how she was moving to Australia for a few months and wanted to confess her feelings before she made the trip.

The note was found by Reddit user u/ho_riene who only posted it on the website this week.

She shared it with the caption, “Found this in the back pocket of a seat on an aircraft I was cleaning last year. Where ever you are, I hope it went well for you.”

The full note says:

“If you’re reading this, hello 🙂

“My name is Andrea and I am incredibly bored. Right now this flight is going from Miami to DC. I’m 21.

“So I bought the ticket last night at 4am because I have a huge crush on my best friend.

“He is flying from Boston to New Orleans and has a layover in DC.

“I actually live in DC and was gonna go up soon anyway so I thought why not, I’ll surprise him at the airport during his layover.

“I’m gonna tell him I have a crush on him. Bold move right?

“But see I’m going to Australia for a semester abroad in 4 days and I won’t see him for 5 months so it’s really the last chance I have.

“I don’t really know what I’m gonna say but I’m just gonna wing it.

“Why not – I mean I’m leaving so who cares I dunno man wish me luck whoever you are.

“Yeah yeah I’m lame for writing this on a barf bag but I’m bored, my WiFI doesn’t work, and I’m nervous as f**k so this is me venting.

“The enormous Starbucks pumped with caffeine probably isn’t helping either.

“Anyway hope this has made your flight a little less boring.

“Do me a favour and do something crazy today like I am.

“Good luck whoever you are. Andrea.”
