Next month, I will be flying SAA within South Africa on the JNB-CPT route. It appears that the majority of flights on this route are operated by 737-800 equipment. However, a handful of frequencies are operated by Airbus and Boeing widebodies. Being an airliner fan, I naturally booked myself onto the widebody segments and will be traveling in business class on a combination of paid tickets and Delta Air Lines award travel. I am assuming that the widebody aircraft are primarily used on long haul flights and operate domestic segments between these flights. As such, I am somewhat concerned that these domestic widebody flights are prone to delays and equipment changes owing to their primary use on international flights. Is my concern justified?
FYI, I am booked onto the SA 321 (JNB-CPT on an A340-600) on Oct. 21; SA 346 (CPT-JNB on an A340-200) on Oct. 25; and SA 352 (CPT-JNB on a 747-400) on Oct. 31.
