I flew MAD-ACE-MAD over Christmas. The outbound flight was a A320 and the seat comfort and catering were excellent. My return journey was on an MD87, the seat pitch was awful, when the seat infront was reclined, it was dificult to get the tray down.

Do JK have a standard seat pitch and I was unlucky in row 18 of this aircraft, or are some aircraft configured for charter traffic?
