I do like a drop of booze, but TBH I can't much tell the difference between anything that's over £10 a bottle retail.
One notable difference would be the Salon on JL F which made me raise an eyebrow.
As others have mentioned before, it's probably not a good use of funds to pay an extra £1k in airfare to get an extra £50 quids worth of booze unless your time\comfort\income ratio is on the billionaire level.
I am not criticising, it would be disengenuous of me to do so given my history of sampling premium travel, but sometimes it's worth a rethink to see if you can get more life experience for your money in other ways.
Unless all your travel is paid for by someone else, in which case of course it's "free".
