I don't think first is wasted - especially on the long hauls even if business is only available out of AU for example. The ability to lie fully flat and sleep comfortably is the main thing about first, then ground services (TG's buggies and being able to skip to the front of security lines are worth the investment). Food and alcohol? Meh. Unless you are on someone like LH or LX where they really push the boat out to offer something unique (especally LH - although they don't always pull it off), then food is food, and the main benefit is being able to get it over quickly and sleep!
Depends. If you can sleep even on a flat slope, J is very much passable grade and worth pocketing the change if you so feel that way. (Yes, if you've read another thread on this forum, I'm one of those who
can sleep on a sloped flat bed successfully, and have taught at least 3 other people successfully on how to do so! Not to say it's for everyone.)
If you can sleep in Y then one should
never have any troubles sleeping in J (it is the exact same experience in a wider chair, at the very worst!)
The ground service with TG F definitely is excellent (notwithstanding the golf buggy service to transit and then from lounge to gate (if done correctly)). I'd be tempted to put a house on bet that
JohnK's mother is not the best in navigating airports (especially new ones) with seasoned skill, so something like TG F to look after her is nice, though suffice to say
JohnK has successfully sent her on a trip before and she has done quite fine on her own. My folks... I'll be stuffing them with airport info, since they will not have such a concierge service at all stops anyway.
For me... I know that my father drinks but not a large-ish amount, and my mum is a teetotaller. Dad was the hardest nut to crack in convincing to try First - he was happy with Business. Wasted on them? Maybe, but I hope to at least give them the satisfaction that they tried it. If they return home, I ask them how was it and they say, "Not bad," or, "Underwhelming," or, "Not worth it," then so be it, but at least they tried it (and the next "gifted" trip will be cheaper
). I'm not expecting them to come home and declare resolutely, "Nil Economy by choice from now on!"
(and by darned I'll fall out of my chair if it so happens!)
