If your friends don't have mounts of their own, you shouldn't run dungeons with them.
That's a little harsh dont'cha think? Some people don't have access to NX cards and since when did which mounts you had determine your fighting ability? I've fought with several people who do perfectly fine in dungeons runs without any pets.
iAki, Pelican and Magic Carpet are nearly the same. Same bag space, both two-seaters and Pelican only has 1 more summoning minute than Carpet. Although the Carpet does have slightly better base stats but I don't think that matters. So whichever one you like, methinks. I personally don't care for the Eagle myself either.
