Certain moments are indelibly stamped in one's memory. Your first kiss. Your first car. And for many travellers, their first upgrade.
For me, that first upgrade came during my 15-odd years as a technology journalist and editor.
Jetting around the world – mainly to Asia and North America, sometimes to the UK and Europe, and most of the time in business class – was part and parcel of the job, especially during the boom years of tech, and no doubt planted the seed for my eventual shift into writing about business travel.
It was in early 2009, and just weeks after Qantas began flying its then-new Airbus A380 on the 'Kangaroo Route' between Sydney and London.
I'd been flown to London for a smartphone media launch, with the trip booked in Qantas business class, but on checking in at Heathrow for the return flight I was upgraded to first class for the London-Singapore leg.
The spacious suite, with its unique 'swivelling armchair' design and cocooning layout, was a massive step up from Qantas' two-abreast business class – even if it fell short of the mark set by Singapore Airlines and Emirates, the only other airlines flying the superjumbo at that time.
And I'm not ashamed to admit that despite the A380's late evening departure from London, the younger and greener me stayed awake for as long as possible during the 13-hour trek – after all, I reasoned, it would be a shame to 'waste' the upgrade by sleeping – so as to soak up every aspect of this A380 first class experience.
To a large extent, this typified some of the best attributes of an upgrade – such as being a completely unexpected 'surprise and delight' moment – although there are also times ahead of a long overnight flight or at the end of a gruelling day, when an upgrade, even from economy to premium economy or business class, is especially welcome.
So we're asking Executive Traveller readers – after all, you're certainly no strangers to that bump-up – to share your best upgrade, and why it was so memorable.
