In response to the pressurization failure, Allan decided to remain at 2000 feet, but the flight was cleared to 3000 feet as a result of the controller mistaking Flight 2120 for a Saudia flight that was also reporting pressurization problems due to Captain Allan mistakenly identifying as "Nationair 2120" rather than "Nigerian 2120", a mix-up that lasted for three minutes but was ultimately found not to have had any effect on the outcome.
En resposta ao fallo de presurización, Allan decidiu permanecer a 2 000 pés, pero o voo foi autorizado a 3 000 pés como resultado de que o controlador o confundise cun voo de Saudia que tamén estaba informando de problemas de presurización debido a que o capitán identificouse por un erro como "Nationair 2120" en vez de como "Nigerian 2120", unha confusión que durou tres minutos aínda que finalmente non tivo efectos no resultado final.
