As usual many people haven't read the original post properly. The OP is talking about travel time to and from planets. Not travel on planets.
I agree that travelling on a planet over distance can be a great immersive experience but the way you currently have to get into your ship to travel breaks the immersion completely (described in detail in OP).
The pointless long runs through empty spaceports are the worst of it. There must be some technical reason (eg pre-loading planet data) but it's certainly not an improvement to gameplay and as originally stated a throwback to the bad old days.
Though I do like the fact that you don't have to bind yourself to one particular quick travel spot - nice change which obviously came late in the game development as the tips still tell you to rebind to a new location.
By the way - if you join warzone then get booted from the warzone you will appear in the hangar at fleet, not your original location. A good way to get a free ride to the fleet. I've never done this deliberately, only had this happen because of the shocking load times on warzones.
