Gees BNEA320, not another 'what if' thread.
Canada 3000's original focus was on shipping Canuck's to Caribean Islands and Mexico in their winter and ex-pat Brits to/from the UK in the British summer. They were NEVER a low cost carrier. Most SLF have come to realise that an advanced booked economy flight, with seat, baggage, IFE and refreshments, is generally not much more expensive than a low cost carrier once you have added on baggage, etc.
