We tested all the top players, on routes that run the gamut from simple to complex, to see where each type of site excels. Here's what we found.
It's no wonder that even the most skilled Web surfers find booking a flight overwhelming. First, there are the airlines' own sites; next, the major booking sites, such as Orbitz, Expedia, and Travelocity; and, finally, the aggregators (Mobissimo, Kayak, and Sidestep), which search all sorts of suppliers for deals. So where should you turn?
Difficulty Level 1: Seattle to Phoenix
Winners All the aggregators and booking sites found nonstop Alaska Airlines
flights: on Mobissimo, Sidestep, and Alaska's own site prices
started at $239; on Expedia, Travelocity, and Orbitz, at
Losers United, by about $20— its one-stop service
costs $260 round-trip.
Lessons Don't worry too much about relatively simple routes. If there's an
obvious bargain out there, it will most likely appear with little price variation on most—if
not all—aggregator and booking sites.
Difficulty Level 2: Los Angeles to Boston
Winners Sidestep, for its trio of offerings:
it listed the cheapest round-trip route (two stops each way, on Midwest for $281), gave buyers
the option of a great direct flight on Delta for $349, and offered nonstop service on JetBlue
from Long Beach for $322.
Losers Expedia, because it listed Sidestep's
$281 Midwest flight for $306 and didn't offer the runner-up for least expensive: a $300 one-stop
flight via AirTran available on all the other booking and aggregator sites.
Lessons If you're flying on a route that JetBlue services
(even through a secondary hub), turn to an aggregator. None of the major booking sites list
any JetBlue flights.
Difficulty Level 3: San Francisco to Charleston
Winners Sidestep emerged victorious, locating
the best values from both the San Francisco and nearby Oakland airports—$584 and $526,
respectively. Sidestep and Kayak also listed several flights
into Hilton Head, 60 miles from Charleston, for $200 less.
Losers Mobissimo listed numerous well-priced
flight options, but these led mostly to cheaptickets. com itineraries that were no longer
available. The first available flight was $592. Plus, the site didn't list any flights into
Lessons Choosing alternate airports can mean big savings.
Most sites let you search multiple airports, but Sidestep and Kayak make it exceedingly easy,
allowing you to quickly price out flights to and from other area hubs.
Difficulty Level 4: Atlanta to Buenos Aires
Winners Mobissimo found the best price,
$990, with stops in Miami and São Paolo. Even better, the site found a $1,115 nonstop
flight on Delta for just $125 more.
Losers Delta, for listing the same nonstop
flight that Mobissimo found, at $226 higher. Travelocity also found that
Delta flight—for an additional $230.
Lessons Although prices on aggregator and booking sites
are, for most searches, relatively equal, with more complicated itineraries, there's always
the chance of a cut-rate bargain showing up on just one site. If you don't want to miss out,
check all the sites.
Difficulty Level 5: Dallas to Delhi
Winners Orbitz and Sidestep had the best mix of price and itinerary, with a combination British Airways and American
Airlines flight for $1,476. For $500 more, American Airlines took nine and a half
hours off the round-trip journey; Orbitz and Kayak also
found this flight.
Losers Expedia, for flagging an American
Airlines flight that was longer and more expensive than what American offered on its own site.
Travelocity's most affordable option was a Continental flight for $1,904.
Lessons For complex, multiple-leg itineraries, booking sites
like Orbitz are the best at putting together inexpensive flights using more than one carrier.
The airlines' own sites sometimes lack this capability.
