Bus Tickets from London Heathrow Airport to Newcastle University

I actually missed my bus from Heathrow due to delayed of my flight from Casablanca because of bad weather. I got to Heathrow around 7:30pm. However my scheduled bus from Heathrow to London Central station had left by 9pm. Thereafter,I ordered for Uber to take me down to London in order to join my connecting bus from London Central Coach Station to Newcastle. Unfortunately my scheduled bus had also left few minutes after my arrival at London Central Coach Station. All effort to book another proved abusive. However, I have to book another bus to Newcastle with mega bus . First time in Uk with such ugly experience wasn't fine by me. All expenses to book my bus from Heathrow connecting to London final destination which is Newcastle is a total waste.

Everything was good except from Victoria to NCL during 7 and 1/2 hours we had only a break of 10 min and that too at deserted bus stand so had to stay hungry throughout

Perfect trip. Only problem I found was that is was cold on board the bus

Bus from Heathrow to Victoria was 1 hr 40 mins late which meant I missed my 18.00 connection to Newcastle , I did manage to get on a bus at 19.45 again 15 mins late and got into Newcastle 2 hrs later than scheduled which meant I had to get a taxi , no soap or water in toilets which is very unhygienic and something would not even expect in 3rd world country , driver was particular rude to a woman travelling with with young daughter - all in all unbelievable
