I have a large suitcase just over 82cm and I know in terms of linear dimensions, it’s approx 170cm. I’ve booked a Singapore Air flight between Syd and Europe in business class and there are some linear restrictions mentioned as a footnote on my ticket but that only seems to apply to flights to/from the US. As long as I’ll be under the weight limit, am I correct that Singapore Air doesn’t police the dimensions of checked baggage between Aus and Europe?
