I am set to fly IAD to LHR on the 122 daytime flight in a few weeks, and return TLV-EWR-DCA. I sprained my left arm/shoulder badly a month ago and am not certain if it will be fully healed by the time I fly. I'd hate to.postpone even if UA will waive the change fee as I got an amazing fare that seems to have subsequently been pulled, and assume that any rebooking would cause a re-fare.

For the most part, I think I can manage without assistance. The one thing I'm worried about is my ability to grab my bags off a moving luggage belt on arrival at LHR, EWR, and DCA. Will UA provide assistance with that (would they even have staff around in the area who can do that?) and is that something I shou!d request in advance of travel?
