When selling an onboard discount, what is the passenger's companion not entitled to?

When selling an onboard discount, the correct understanding is that a passenger's companion is not entitled to a disability and mobility impaired discount. This is because the disability discount program is specifically designed to assist those individuals who are themselves disabled or mobility impaired. It recognizes their unique needs and provides financial relief directly to them.

Companions or travel partners of passengers who qualify for such benefits typically are not afforded the same direct discounts, as these are intended solely for those who demonstrate eligibility based on specific criteria regarding their disability status.

In contrast, regular fare discounts, senior citizen discounts, and children's discounts are generally more inclusive and can apply across a broader range of passengers, thereby allowing companions to benefit from those specific categories when applicable. Thus, the correct choice underscores the targeted nature of disability discounts and the regulations governing their use.
