We expect any sharing would be limited to alliances for now, and even that would be partial data exchange.
The problem isn't Star Alliance, the problem is United.
Air India's entry into the Star Alliance is a watershed, but the ongoing FAA downgrading of India's air safety rating looms as a cloud over the event.
Great new terminal, but what Heathrow really, really needs is another runway.
Round-the-world tickets aren't a frequent purchase, but they're an excellent way to market an alliance's size, network, and amenities.
In addition to getting Oneworld member airlines as miles redemptions possibilities, US Airways will still retains, for awhile at least, about a dozen codeshare partners outside of the alliance, making for more redemption opportunities. The extra ones likely won't last for long, but flyers can consider it all a merger bonus for now.
Oneworld makes a strong showing, and as American Airlines continues to grow, it would appear to offer the strongest product of any of the three alliances. The wild card, though, comes from the non-traditional alliances being built from the Gulf states.
Air India would benefit from entering the Star Alliance but its persistent financial troubles are not a real confidence booster.
Is the Star Alliance's future just about continuing with the cumbersome process of adding new airline members here or there, or does it have to formulate new strategies to confront the growth of Emirates and Etihad, for example, which aren't as enamored with traditional tie-ups?
