I find calling flights to Australia “regional” is pushing the limits a bit. For most Asian airlines they 8 hours plus – that could get one across the Atlantic. However a circle round Taipei and Jakarta or Hong Kong and Japan are reasonably regional. Certainly CX has flat beds for Australia and India. Shorter haul seating varies by the hour as they decide which configuration to throw at you. You can’t book any with certainty. Having said all that, Asian airlines Bizzo seats are way ahead of anything used in Europe. As a consequence I try to minimize (eliminate) my intra-European flights whenever possible.
