I flew IB, IB as BA and AA as BA on April 23rd. I'm interested in seeing when those will post! (I generally try to avoid codeshares, but this purchase allowed me to buy one way travel LIS-MAD-JFK-SFO for much, much less than J any other way, and even most coach and all premium economy flights - we traveled SXM-LIS via motorsailing vessel, so no open jaw possible and needed the single / one way tickets.)
