National Express Heathrow Portsmouth recent customer reviews
I saw that as per the trains were disrupted as it is Sunday. My son advised me to check out National Express. This will definitely be my choice of transport in the future . Arrived and left on time, comfortable journey and seating with a direct service to my destination. Great service. Thankyou
Susan G.
The bus was late arriving. I was very cramped in the seat. The terminal announced the stand wrong and I almost got on the wrong bus. The driver drove with 2 feet and kept braking all the time and I was getting very car sick.

Perhaps have a direct coach from the airport to the south in order to avoid going to London and then down.
