Our Tuesday 1/18 flight (United out of EWR) has just been cancelled.
Next available is Wednesday 1/19, same time, but no Economy seats available so we had to upgrade to Economy+..
We had submitted our EHAS forms, my wife Cleta's was approved almost immediately - mine is under review.
However, since arrival date has changed, we have to start from scratch by filling out new forms.
Bottom line is we'll have more legroom but one less day of vacation.
