Mrs Trappy, Junior Trappy and myself are off to Tampa via Washington and I wanted to know the best way to get us upgraded on the internal flights. Obviously I know UDU will only apply to one passenger but if I split the PNR then I will not get the E+ for them on the TransAtlantic. I can happily use a Regional Upgrade for the additional person but will the system see the other two people automatically for the "free" UDU?

Thanks in advance
