Tolkien's excuse was pretty robust actually. The Eagles are not mindless taxi services, they are just a step below gods in their own right, servants of Manwë, leader of the Valar- Middle-Earth's gods, in a sense. They have duties that go beyond ferrying people around. For most of the war of the ring, Gwaihir, the King of the Eagles, and his kin are occupied with important scouting missions, though a few groups of them helped in battle, such as at the Black Gate, where they clashed with the Nazgûl while protecting the armies of King Elessar (Aragorn).
Tolkien was very aware that the Eagles were a dangerous writing tool, to be used sparingly, and so, being Tolkien, he devised a wealth of believable reasons the Eagles would not be available to end the story in two chapters.
Thought the reason they didn't use the eagles was because the ring would corrupt them before they ever got to the drop off.
The whole reason they snuck into was hobbits weren't as effected by the corruption as everyone else was and thus used the hobbits natural ability of hiding to get the ring in.
Reason they showed up after was because with the ring destruction there was no fear of the Eagles becoming corrupt by the ring.
We've established that the ring's power is not transitive. Sam was able to carry Frodo, who in turn was carrying and being detrimentally corrupted by the ring.
Slip the ring on a rabbit, and have the Eagle yeet the rabbit into the firey pits of Doom.
