Why does the SATA website show fares lower than the ones offered to the group?

SATA offers promotional fares on several routes to its individual passengers. These are reduced value fares, which exist in a limited number of seats and, as such, imply advance payment, do not allow change names, do not allow date changes, and are subject to seat availability on the same class of service (so that a fare difference would not be needed), plus change penalties.

How can I request a group quote?

Pay attention to the GDS fields: and Office ID / PCC: which must be filled in Amadeus in the GDS field and PDLS40128 in the office ID/PCC field.
