Most airlines will allow you to bring certain pets on the plane, but you'll need to buy an approved carrier for your animal and will need to bring the animal through the metal detector with you. You'll also need to pay a fee for your pet; larger animals have to go into the cargo section.ou're allowed to bring food on the plane, but because you cannot bring large bottles of liquid, you'll have to buy drinks after you go through security.
However, if the test includes the EtG testing, this can detect recent alcohol use for 26-80 hours depending on which reference you believe.
Alcohol itself stays in your system for 1-1.5 hours for each drink you take, plus approximately 1 hour delay for the initial drink -- this is when it's detectable in breath and blood, and when it will affect you. It then stays in your urine for another hour or so, where it's detectable in a urine test.
