It looks like United is on a roll this evening. Cheap flights to Cairo, Egypt (CAI) are showing up at $802 for round-trip flights from Houston (IAH). No stopover component found in the fare basis rules, but you should always double check. I may have missed something. United and Air Canada seem to be handling the bulk of the traffic.
NOTE: This route will no longer be actively monitored. From a pure CPM basis, flights from Houston to Cairo will always seem deal-worthy. If this route isn’t on a Lufthansa / United sale, it will be on a KLM / Delta / Air France sale. If it’s on neither of those, you can get it for about $650 on Turkish. I’m leaving this as an “active deal” indefinitely. I will not send out notifications unless the route falls below $650 round-trip.
