Searching for and old flight

[roeo]

So I'm making a log of all the flights I've taken and so far I'm doing great, as I have been able to find data of every flight and aircraft, except for my first flight ever. As I was a bit young I don't really remember the aircraft type neither the registration and can't either find it anyplace on the internet.

That way I`ve decided to ask here for any help in the form of recommendations or if anyone is able to obtain that info. Here is all I have/remember of that particular flight, which is almost everything except for the aircraft type and registration:

Date: 2007-08-22
Flight: UX9090 - Air Europa
Route: MAD - FUE
Dep: 07:40 (as stated in the boarding pass)
Arr: 09:25 (as stated in the boarding pass)

Hope you can help me!!

According to some quick research, Air Europa had 737-800, 737-400, 767-300ER, and A330 in 2007, among others. The most likely plane that had been on this route would have been the B738, as most of the B734s were retired in early 2007. In terms of registration, I don't know of any places where this information can be found as Airlines don't even keep and let alone publish information like that for over 15 or so years, that I am aware of.
