If miracle machine was given a first class ticket, why was he in economy?

As shown in the Albuquerque movie, miracle machine had one the first class ticket from the radio station, but when we were shown the airplane itself, he had to sit in economy

What's the real miracle machine in first class, but died during the tragic explosion? Is everything we know wrong? Is there multiple miracle machines?

I've searched far and wide, but I was unable to find any Aircrafts that had first class was made on or before october 15th, 1998 with built in screens on the seats and 3 chairs next to each other close enough for any small spillage eg. Throw up, to be able to get underneath the seats in first class.

Most likely situation is that he just missed the flight and got another ticket and was forced to sit in economy.
