commitment. Each ring is one type: the inner band is what flies today, the
outer bands are aircraft on order and under option.

On firm order

regional aircraft operated by partner carriers are excluded. Options are
rights to buy, not commitments, so the order book and the delivered fleet
should not be read as one number.
