For France '98, which was done by post, anyone who had been to at least two away qualifiers, or the game that Estonia didn't turn up for, was guaranteed tickets for all three games.
One away qualifier got you a Brazil ticket, which is what I had via the Sweden game in Gothenburg. Everybody else in the Travel Club got one of whatever was left.
I actually flew back and watched the Norway game in my house before spotting a newspaper advert for a scuffed charter flight to the Morocco game, including match ticket, which turned into an epic trip day trip on a giant ramshackle antique plane with free-for-all seating and a smattering of footballing celebrites on board, such as Davie Hay and Roddy Grant, who turned up in his St Johnstone tracksuit. The airline was Peach Air, which I later found out was genuinely an anagram of 'Cheap' which made sense, on reflection.
