  You summon a Flight of giant eagles (one per three Caster Levels, maximum of six; Bestiary 118) to ferry you and your allies across the skies. The eagles avoid combat if possible but defend themselves if attacked; if the eagles attack, the remaining duration of the spell changes from 1 hour per level to 1 round per level (so if the spell had 5 full hours left, the eagles remain in combat for 5 rounds before the spell ends).
