Well, here is a suggestion for a little change in the Route System within Spain.
I´ve seen scheduled flights departing from Barcelona (LEBL) to Zaragoza (LEZG) which are operated with a class 4 aircraft. The distance between these two cities is no longer than 300 km, which actually, in my opinion it´s too short to be flown with a class 4 aircraft. I suggest using a class 3 or lower for that route.
On the other hand, the route between Madrid and Barcelona is operated with a class 3 and it takes a lot of time to fly from one city to another if we consideer that in reality, airlines uses a jet aircraft. Actually the air corridor between these cities is one of the crowdest of europe (Iberia´s Air Shuttle). How about a class 5 for that route?
Finally, It happens the same between Madrid and Lisbon (LPPT), although with EuroHolidays is operated by MD-80.
I think this routes should be reviewed, and I explain this because since I started flying for EHM, this surprised me a lot, and I wanted to take this opportunity, now that this topic has been opened.
Regards.
