Well, I'm nearing the end of my trip and have had quite a lot of bad luck getting to the spotting locations first thing in the morning. Not understanding a word of Spanish hasn't helped my situation.
Day ONE. Forecast suggested RWY 07L for arrivals so at 7am I made my way to Terminal 1 via the underground line. When nearing the airport, I noticed everything was landing on RWY 25R. Doh! So upon getting to the airport, I tried locating the PR3 bus stops which would bring me to the Southern side spotting platform.
Turns out the bus stop is 1km from the terminal and you are required to press a button to call the bus. Long story short button was pressed, bus didn't come, so I started walking the 4.5km walk to the platform. (3 minutes after leaving the bus stop, the bus drove past! Doh again!)
Skip forward to 9am and I had just made it to the platform when the RWY changed direction rendering the spotting location useless.
Had to catch bus back to the airport and back to the original Terminal One location.
Basically after 3 hours of faffing around, no spotting started until 10.30am, missing most of the interesting traffic.
Day TWO. After making 100% sure the RWY movements were correct, I set out to the RWY 25R platform for sunrise at 7. Upon trying to catch the PR3 bus, this time the driver gestured saying the bus didnt operate to that side of the airport until after 9am. DOHHH! Either wait 2 hours or again walk the 4.5km distance.
Again I opted to walk and this time made it to the platform for 8.15am. Thankfully more lucky this time and got a full 8 hours of spotting completed along with some interesting movements including Red Wings Tu204 and various of special liveries.
Now very tired, a tad drunk and a bit delirious, so excuse the long rambling reply. My advice for anybody spotting at BCN... hire a car or get a taxi!
