Your intuition knows better about this dream. You are receiving a message from your subconscious mind and these are very personal. I can not know about this meaning more than you do but still, I will share with you my perspective on this kind of dream:
Airplanes could be a symbol of your goals. It could be that you are going through a plan in order to reach your goals and that this is a positive omen or confirmation for you. These goals could be very related to freedom that you seek in life. Also the different colors that go with the planes could suggest of a new state of consciousness or spiritual awareness which will bring you closer to these goals.
Again, you know more. I suggest you listen to your intuition and see what resonates with you.
