Air Horizont (HAT, Zaragoza) is on track to take delivery of its maiden aircraft, a B737-400, ahead of its planned launch in May. Skyliner Aviation reports 9H-ZAZ (msn 25349) was recently spotted at St. Athan airport in the United Kingdom following its repaint into the start-up's colours.

The jet is chartered from an unknown Maltese firm as Air Horizont has yet to secure its own Air Operators Certificate (AOC).

Once operational, the Zaragoza-based carrier will serve Seville and Alicante in Spain as well as Munich and Rome Fiumicino in Germany and Italy respectively.
