That's right. The 73G code is assigned to the 737-700 Series aircraft so that people don't get confused. 738 obviously means 737-800 but 737 doesn't mean 737-700, it can be any 737. I think the letter G was chosen because G stands for Generation, coming from Next Generation. Continental, Southwest and Alaska have 737-700's.
