I doubt it would be economical for EK
to bring a new aircraft type into its fleet for a stop-gap duration of time. The three ex-UA aircraft available for sale have been parked since post 9/11, and are in need of SIGNIFICANT maintenance work to be brought back into servicable condition. Also, as mentioned above these aircraft are Pratt powered while EK
's current 744F fleet is GE
The only feasible way to bring in B744 capacity would be an ACMI contract (similar to what Iberia did with their recently returned 744's with Air Atlanta Icelandic), but I am not sure whether Emirates would be interested in this type of option.
