UA left a voicemail for me asking me to contact them about my July Flight from LA to Rome in Business/First “P”. LAX-EWR-FCO (737-800, 767-400ER)

I looked at the flight and it appears that their latest schedule change has left me with <30 minutes connect time in EWR. My guess is they will want me to change the flight. I’d like to change it too, since I think it is too little time to make the connection.

I want to call them back with a new flight in mind, instead of them telling me where/when they want me to fly. There are a ton of alternatives. I found a UA flight on a 777-200 LAX-LHR and then on BA to FCO on a A319.

Assuming that’s why UA is calling, do you think I will have options on which flight to change to? Will they charge me a fare difference even if the change is “initiated” by them?

Which would you rather fly international business class on? A 777-200 or a 767-400ER? I definitely want a lie-flat seat.

Thanks for your help.
