Better to purchase Premium Economy outright or get Economy and the upgrade at a later date?
Just checking to see if it's better to purchase Premium Economy outright or get an Economy ticket and then upgrade at a later date (within a week of purchase). Is the pricing the same or will it be significantly higher? Anyone who has done that and can provide feedback?
My flight will be DXB-LHR and back. It's a work trip - company is paying for the Economy leg.
Update - Purchased the Premium Economy outright to avoid any surprises later on.
