So when Easy chartered a 757 for the summer season a couple of years ago?
True, but then again, I doubt it would have had an EZY call sign?
The amount I get that type of conversation surprises me. A slip of the tongue, or does the pilot/co-pilot actually think he/she's flying a different type of plane? Whether you're in an A319 or A320 means diddly squat to a radar controller, or probably even the ground handlers, but surely it's handy for YOU to know exactly which one you're flying???
Actually it means more to the ground handlers than anyone probably, the loading procedure is different!
Whilst it sounds a bit "silly", don't forget that it looks exactly the same in the pointy end so it is easy for a slip of the tongue to occur when you fly a 19 99% of the time.
