I am flying on on a Friday from Heathrow to usa. My flight departs at 11:55. I am trying to figure out how to get to Heathrow from Southend since I am smallish woman carrying a big suitcase so I am not sure if I can make it on regular public transport trying to carry the suitcase. I have looked at the National Express but it does not get there until 11:40 so that is not an option.

Am I missing an option? Is there another bus?

Cabs are so expensive all the way from here. Is there a car share option that might be cheaper?

thanks you for your help.
