How much more space do the Betsy seats consume than, for instance, the LH seats? I've only had them on the 744, but my understanding is that they fit them on the 340 in a 1-2-1 configuration. A little bit less pitch, apparently, than upstairs on the 744, but I thought they were the same seat. It seems as though they could do it if they wanted.
Maybe it's simply that SQ is only putting them on their megatops? (or is that no longer the case?) And that, to date, they don't have to compete with "suite" seats on most of the non-stops they fly with 340's, e.g., UA to SFO, SR to ZRH, AZ to FCO, AC to YYZ.
I'm not a frequent CX flyer, but I would love to see them come to SFO to pressure UA to get more of their suites more quickly.
