Emirates...
It could be imagined the word "launch" in the context posted perhaps may well read as "announce" & therefore commencement of bookings.
UAE33 was some five full months between announcement & start & actually could be counted as seven as it was announced 20.12.17 & commenced 6.6.18.
The second daily is certain & fits with all the mood music from the STN CEO too.
The more interesting subject is the daily timing/schedule & cabin fit of the second as UAE33 is timed & cabin fitted for a specific market that UAE & MAG very correctly identified.
