A friend, Frank Cordes said: "You always knew it was match day as John was dressed in his black suit and white shirt."
Friends of Alder said that he was a permanent fixture at their football games, and that Newcastle had lost "their number one fan".
The 28-year-old Newcastle United fan was on board with John Alder, and was also believed to have been travelling to New Zealand to watch Newcastle United's pre-season tour of the country.

"[Richard] was on his way to Perth. When we were looking at flights together, there was this one that stopped in Amsterdam and we thought it would be perfect.
"He was diabetic so we thought it would be a good chance for him to do whatever he needed to do and maybe even go out and have a ride on the bikes and see Amsterdam. He was really looking forward to it. I took him to the airport at 3am myself, to fly to Amsterdam.
"When I first saw it on the news, my heart dropped. I just thought, oh god, oh god – I couldn't believe it. We were hoping and praying he had fallen asleep at Amsterdam and missed his flight.
"You think you've got problems and them something like this happens and it all just takes over. I can't even bring myself to look at a photograph of him. We are beyond devastated. It is such a beautiful sunny day but our lives have been torn apart."
Leeds University issued an official statement:
"We are very saddened to hear the news that one of our students, Richard Mayne, is believed to be a passenger on the flight. Our thoughts are with Richard's family and friends. Richard had just finished his second year in maths and finance and he was doing well with his studies. Staff are working with the University's counselling service to help students who are affected by this tragedy and we will do all we can to support them."
