Narrative:
Air carrier X departing mia for tgu. We were cleared to FL330 from mia center and then handed off to havana center. We requested FL410. They gave us a heading of 210 degrees climb to FL410. As we started the climb, we noticed aircraft Y on TCASII 1500 ft above on the nose. At that point, TCASII RA commanded a climb. We complied and missed by 1000 ft and 1 mi.
