I think my company has the best solution.
economy for short haul (I do business with a FT trick and no one bats an eyelid) and WT+ if it is a certain bit more than Y.
However, those are the rules. The reality is...... every year I get an annual budget. Don’t book club but you can upgrade with miles. Book anything else but try and get value. Oh and don’t be a prat or take the piss.
otherwise suit yourself. Oh and if you travel at the weekend, stick a couple of days off in you diary when you want. No approval required. Just don’t take the piss.
