Any Tips/Info On Possible Interline Upgrade?

[DAL745]

Traveling for the first time on Royal Caribbean (interline rate). Wondering if any other interliners out there have been lucky in receiving an upgrade? I know some lines offer that on a space available basis similar to our industry's non-reving policies. If any one has any info they can share it would be greatly appreciated (ie: when to request, in advance or during check-in, etc).

Your best bet is to keep an eye on the interline rates and if a better cabin category at a better price comes up have your travel agent upgrade you (at the new rate). If you request an upgrade at check-in or onboard your interline status means nothing, you pay the same as everyone else for an upgrade. Go Delta!

Thanks for the info!! Very much appreciated. The rates for our particular sailing have been few and far between... right now we are more than grateful that we have the booking at a great rate. Thanks again.
