Nice pics. First is an A330, the wings give it away, still trying to work out the airline.. 2nd is a CO B764 I’m pretty sure.
The jurys still out about the CO. On magnifying the picture – you cant see the two tone white /grey colours which CO has. The tail fin is very narrow like a 777 and I cant see the extended wingtips of the 764. oh well, guess we’ll never know.
