Sneaky airline passenger's carry-on hack sparks debate over flight etiquette

While airlines have a variety of baggage policies in place, it is standard for carry-on roller suitcases of a certain size to be stored in overhead bins for flights. 

Posting in "r/delta" forum on Reddit, a flight passenger asked, "How did FA [flight attendants] miss this?"

"Suitcase was 'hidden' behind the curtain that separates C+ and first," the person wrote.

"Multiple FAs passed this before departure and during the flight and I didn't notice a single one say anything about it," the person continued.

"The carry-on abuser has outed themselves here. We all despise you," commented one person.

One user joked, "Pay no attention to that case behind the curtain."

"Frankly, I've seen stuff like this lately and I guess now it's OK for people not to bring their seats back to the original position in prep for landing," said one user. "The flight attendants do their 'walk' and I'm convinced they see it but they walk right by."

Another Redditor commented, "Mind your own business, carry-on narc."

"Mind your business," echoed another.

"Carry-on baggage may be stowed either against a passenger-class divider or bulkhead if both are stressed for inertia loads, if it is restrained from shifting by FAA-approved tiedown straps or cargo nets," FAA's bulletin reads.

The bulletin also states there should be "preboarding scanning to ensure that size and amount of passenger carry-on baggage is in accordance."
