 If you liked
Tenkuu no Shiro Laputa

 ...then you might like
Suisei no Gargantia

Both display several similarities:
- Similar landscapes and setting.
- Pirates and slice of life.
- Similar Air engines that humans use to fly.
- A protagonist coming from the "sky".
While Laputa focus on romance, SnG focus on friendship, and the latter has Sci-fi with Space/aliens theme while Laputa remains on Fantasy genre. Personally, I found Gargantia´s characters more enjoyable, still, both are great to watch, so if you liked one, you may like the other.
