Thank you for clearing that up
. I think I used the wrong words. Actually I was referring to an AD that could last an entire day, depending on the number of applicants. Like you said , an OD only lasts a few hours.
Honestly I do not know a time when Emirates did an OD and an AD in the same day.
Anyway thanks again PrimaveraCero for clearing that out for
Misled
Have a great day
Be well
