Emirates Business Class Codes

[deltahotel]

Mrs hotel and I are flying on the same EK Business class flight later this year. On the e tickets (which were booked separately), one is referred to as Business (I) and the other as Business (O). Anyone know the difference?

Did you both pay the same fare?

[deltahotel]

No, but we're coming home on different dates.

Generally speaking different booking class codes indicate different fare levels (and different restrictions etc) so if you paid different fares that seems the most likely explanation.
