Since you are using an alternative cost to cast a spell from exile this way, you can't pay any other alternative costs. You can, however, pay additional costs, such as kicker costs. If the card has any mandatory additional costs, you must pay those.

Lands exiled this way cannot be played from exile. (Lands that were animated by earthbend will be returned to the battlefield tapped when they're exiled.)
2025-10-02
Tokens exiled this way will cease to exist and cannot be cast.

To airbend one or more permanents and/or spells means to exile each of those objects. For each card exiled this way, for as long as it's exiled, its owner may cast it from exile by paying rather than paying its mana cost.

Flying Rule 702.9

Flying is an evasion ability.

A creature with flying can’t be blocked except by creatures with flying and/or reach. A creature with flying can block a creature with or without flying. (See rule , “Declare Blockers Step,” and rule , “Reach.”)

Multiple instances of flying on the same creature are redundant.
