So I am going to Iceland and it seems like I'll have to have a layover somewhere and then take an Icelandair plane (Boeing 757) to Reykjavik, Iceland....I looked up their fleet and their planes are old, especially the 757 which are between 18-26 years old! I am freaking out...I also found out that Boeing doesn't even make 757 anymore! I get anxious thinking about this....how do I calm down? What helps a little is that I read that the planes have been renovated...such as a state of the art glass cockpit (whatever that means) and screens on every seat...but still :(
