That service is already scheduled year-round.And finally, South African Airways, one of United’s Star Alliance partners, was hit particularly hard by the pandemic. The airline nearly went out of business, and only restarted its flights in September 2021. Its international network is severely limited, with service only as far as Accra, Ghana (ACC), and Lagos, Nigeria (LOS). Prior to the pandemic, South African operated flights from Johannesburg to Washington Dulles (IAD) and New York’s John F. Kennedy Airport (JFK), according to Cirium schedule data. United’s move could be a sign that it sees the demise of South African’s overseas flying as an opportunity.United’s service currently departs Newark as UA1122 at 8:30 p.m. on Sundays, Wednesdays and Fridays and arrives in Cape Town at 6 p.m. the next day, all times local. The return service departs Cape Town as UA1123 at 8:50 p.m. on Mondays, Thursdays and Saturdays and arrives at Newark at 5:50 a.m. the next day.The service will actually end in March, as previously scheduled, but will return for good on June 5 instead of October, subject to government approval.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
