Key Kelly quote from a recent earnings conference call:
"We are in the process [of installing] and it's been slower than I would like. On the other hand, as you know, the take rate among customers on this product has been slow to take off so I don't think we're missing out on anything yet."Southwest is now eyeing a 2013 completion of Row 44 installs; it previously predicted a 2012 end date. But if you need proof that the carrier is moving (at least slowly but surely) towards fleet-wide equipage, check out the Tweet thread (below), and the FlyerTalk forum (this lad spotted two non-trial 737s at PDX yesterday). Thanks @Curbcrusher for the heads up!
