If a flight is delayed and it’s not due to weather, you may be due for some compensation, according to the airline’s contract of carriage. But if the delay can be attributed to weather, you’re out of luck. Guess what they’ll try to blame… So how do you find the truth?
For some reason, some airlines offer the real reason for flight delays to their cargo customers, but not their passengers. But not all airlines do this. In my experience, United and American cargo sites offer reasons for delays — reasons which may differ from the regular airline site. If you’re delayed, log in and check both the regular and cargo sites to see why. If it’s not weather, print-screen, then start negotiating with the gate agent.
If the cargo route fails you, or if you’re looking for some all-purpose flight tracking, I generally recommend flightstats.com and flightaware.com. Flightstats offers great, detailed information on everything from gate information to runway statistics. Flightaware offers snappy live-updating maps and route information for the actual flight en route, but less practical info for the person actually traveling.
