I use Kayak to search flights. Lately I see fares showing up that are labeled "Major Airline". You are unable to see the carrier or exact arrival/departure times (they show a range of one hour or so) until you purchase. For example:
Due to the low price, the full details for this flight are hidden. To offer you this special fare, the name of the airline and exact travel details for this itinerary have been hidden until you purchase the fare. Upon booking completion the airline and travel details will be revealed.
Has anyone booked a flight this way? I'm seeing some attractive prices to multiple destinations.
