I also believe this has nothing to do with the integration and everything to do with further monetization of E+. Case in point: I'm travelling with family members all on award travel. There's 6 of us on 3 different PNR's and 5 of us are in bulkhead and 1 in exit row. This is the only time I've had more than 1 other person travel with me but I can imagine this irks UA revenue guys to no end. In fact, on one of my calls, the agent was adamant that only 2 people can be brought into bulkhead or exit row seats.
