British Airways announced on Saturday that the flights are suspended "as a precaution to allow for further assessment."
Lufthansa said in a statement that "as safety is the number one priority of Lufthansa, the airline has temporarily suspended its flights to Cairo today as a precaution", reported Xinhua news agency.
The British carrier said it cancelled flights to the Egyptian capital for seven days.
Ahmed Fawzi, Chairman of the Cairo Airport Company, told Egyptian newspaper Al Shorouk that British Airways did not inform them of any concerns regarding airport security prior to the cancellation.
He said Cairo airport had not received any notification of British Airways' decision and the cancellation was "an internal affair inside the company."
Egypt's Ministry of Civil Aviation said in a statement on Saturday that it had confirmed that the decision to suspend the flights was not issued by Britain's transport or foreign ministries.
Officials from the ministry said the decision was one of "security and political measures that are concerned with internal affairs, and not those of Egypt."
The ministry said that Cairo airport, as well as Egypt's second busiest Hurghada airport, resulted in "excellent ratings" in a recent security check conducted by British airlines, and that other airlines were operating as usual.
The Egyptian ministry added that it will increase the capacity of EgyptAir flights to London starting Sunday "to facilitate transporting passengers during this period."
The British government has long advised against nonessential travel by air to and from the Egyptian resort of Sharm Al Sheikh, where a Russian passenger jet was bombed in 2015, but has not issued similar warnings against air travel to and from Cairo since.
"Terrorists are very likely to try to carry out attacks in Egypt. Although most attacks occur in North Sinai, there is a risk of terrorist attacks across the country," according to an updated advisory Saturday on the British government website.
The bombing of the Russian jet in 2015, which was claimed by Daesh, killed all 224 people on board shortly after takeoff.
The attack prompted Russia to halt all flights to Egypt for several years and a number of countries including Britain to cease flights to Sharm Al Sheikh, which have yet to resume despite repeated reassurance from Egyptian officials.
