12. Drumming —
One man's seat back tray is another's snare, bass and cymbal. The only drum sticks allowed on planes should be battered and fried. Budumm-bish!

11. Tapping the seatback screen —
"And if you press here, you not only access a whole flight's worth of touchscreen gaming, you also get to annoy the guy in front by constantly jiggling his seat back for the duration."

10. Singing —
OK the violin we can probably deal with. In short bursts. But if he's about to launch into "Nessun Dorma," we have a problem. Amateur singing is not for planes. Or any small enclosed public space, for that matter.

9. Painting nails —
How many no-nos can you fit into one photo? Bare feet? No. Polishing the nails? No. Bright white? No no no. If you have to paint your nails on board, do so in the washroom. And wait there till it's dry too.

8. Ignoring the flight attendants —
"Maybe if we pretend we're asleep she'll go away." Ignoring the flight attendants' instructions and refusing to return seats to the upright position were among the most annoying plane behaviors for readers.

7. Applauding the landing —
There are times when applause is appropriate. Like when you're celebrating the illustrious career of Harvey Keitel. But according to some CNN Travel readers, clapping because the pilot successfully landed the plane is ridiculous.

6. Changing diapers in the middle seat —
Airplane changing tables are there for a reason -- to ensure you don't have to take care of baby's business at your seat.

5. Drunks —
"No, they're not all for you."

4. Overstepping religious turf —
Sitting next to the Pope would be an honor. For everyone else, please leave the religious evangelism at the gate.

3. Talking too much —
You know when someone smiles politely and resorts to watching movies without headphones, your words are being wasted.

2. Over odorizing —
In a plane cabin, everything is condensed and exaggerated, especially the chemical stench of that travel-sized fragrance that's been sitting at the bottom of your bag for the last 18 months.

1. Grabbing the seat —
By a distance, the most annoying thing people do on planes, according to our readers, is grab your seat when they're moving about the cabin. "(It) illustrates how people are oblivious to the (effect) of their actions and couldn't care less about the person in front of them," says commenter robert.
