Please note the following fine print in this years SE Guide.

In terms of MLL access:

1) SE can invite your immediate family, defined as "spouse or children" - not spouse and/or children. How will MLL agents deal with a family travelling?

2) SE can access the MLL when flying Tango, however, the MLL Guest Pass cannot be used when flying Tango. How will MLL agents deal with a SE flying Tango with two colleages and they want to use the MLL without paying the $20 guest fee.

The fine print clearly references which benefits are excluded if flying Tango.
