Sub Posa
Not only are you annoying but so is your sub-standard English.
If you can replace the word with "you are", then the word is you're .
"Your" is a 'possessive determiner'; you clearly do not know the difference. Anyone who has been through full-time education and was paying attention would know the difference.
Pay attention to this: you are a jerk. Go away and annoy some other airline/individual and not Channel Express.
