What option would be best?

I want a dog but I go on holiday a couple of times a year what would be better

A. Go on 2 holidays that are 3-4 weeks long per year
B. Go on 3-4 holidays that are 2 weeks long per year

Note. I do go on a couple of national holidays and for those they will join me.

No I can't take them on my international holidays because I don't trust airlines and I live in Australia and I can't drive across the ocean

If I decide to get a puppy I won't go at all until they are 12-18 months of age.

How to cope with Anxiety on a plane?

I must go on a plane in a few days to visit family.
I have an anxiety disorder ( diagnosed by a therapist) and I'm scared!

My fears are my things will be stolen ( my things were stolen last time I went on a plane and was left with nothing )
And that something bad might happen to the plane ( like it would break or something)
And that I might accidentally bring something that they won't allow
(I'll be bringing clothes, toothbrush and toothpaste, makeup, my seizure medications + painkillers ( both prescribed by my doctor) and a bit of art supplies, I'm scared they won't allow something! Cause once I got into trouble at an airport for bringing deodorant in a metal spray bottle ( that was how I bought it) and I felt so bad! So much anxiety )
