You'll find out tomorrow which actual aircraft you are flying on, when the United website updates with flight status for 2/6. Otherwise, they always post the old config. Make sure to check and change your seats around immediately as I was booked in 2A/B on 01/28 and then reassigned to 10A/D (with no option to move as it was a full flight). Meals seem to already be updated based off my 01/28 flight but further enhancements would be nice, especially to the fruit cup and breakfast bread! Happy travels.
