it's like the 7 year gap with tenrou. they all lost 7 years, but their bodies are still the same.
so even if the dragon slayers are like around 18 years (wendy younger), they still lost the 400 years with the time travel. so they are 400+ years old, even with their normal aged bodies. and so they could not go out the 80+ barrier from freed.
This is quite shaky; I don't see how time travel makes you lose time. Assuming this is simple time travel, they were "detached" from the flow of time, jumping from one point (era) to X777. It is quite different with the body preservation or, by your example, the Tenrou Island incident, in which Natsu (and Tenrou team) "remained" in the flow of time.
Or the answer to this question may lie on what are the exact, specific conditions of Freed's Runes. Although:

another additional explanation could be, that the dragons, who were in the dragon slayer's bodies at this time are definitely over 80 years old.Isterio said:
Many people assumed it was because the Dragons were inside of them, which would explain it.
This sounds plausible.
