I really enjoy flying, and have hardly had any problems with the flight and airline. I just have a problem with the people who tend to annoy me on planes:

1) Passengers who rush the gate when the first boarding announcement is made or just ignore boarding zone procedure. When the gate agent says 'Zone 1 only please' and you see someone with an enormous '4' printed on their boarding pass step forward. I'm actually grateful for GAs that enforce the system.

2) Passengers who stand in a security line for ten minutes then at the last minute choose to get their plastic bag of liquids, boarding pass and stuff out of their pocket holding up the line. Unless you've been living under a rock you should know how to go through security at the airport. Why not at least have the stuff to hand so by the time you get a tray in your hand the line runs as quickly as the security personnel allow.

3) Despite numerous announcements to have boarding passes (and passports for intl flights) ready passengers approach the gate with neither in hand and then spend three minutes looking for their boarding pass which is hidden in the super secret pocket of their rucksack.

4) This isn't just at airport but it seems more prevalent there...people who just dawdle in the middle of corridors or moving walkways blocking the way to those in a rush/trying to beat the crowds to immigration/some other good reason for running through the airport.

5) People who seem to take FOREVER to get themselves sorted at boarding. They stand in the aisle getting every thing out of their carry-on and have to be told by the FA to 'please step into your seat'.

6) People who seem to complete ignore the seat belt sign and leap up before the plane gets to the gate. They rarely appear to be in a rush to get off but just stand in their seat area...and those in the window seats have their heads craned over as they can't stand up straight!

7) Those who just make a mess needlessly. I was on a flight from South Africa to London and the teenager in one of the seats behind me had got a copy of the Daily Mail and spent the flight tearing it up and left it all over the seat and on the carpet around his seat. I know the Daily Mail is a useless newspaper but that's just rude.

8) Premium cabin flights of 1hr+ with no food. Pretzels on a 2hr breakfast time flight is stupid.
I’m sure many people have annoyances on flights, unless I have covered them all!
