Airlines face new rules capping fees to actual costs; families gain free seating.

What it does

This bill requires the Department of Transportation to write rules within 270 days that ban airline fees for changes, cancellations, baggage, seat selection, and priority boarding unless those fees are reasonable and proportional to the airline's actual costs. The rules must specify how to measure reasonableness, must be updated every three years, and must ensure families with children under 13 can sit together without extra charges. Ordinary travelers benefit by paying less for services that don't actually cost airlines much to provide.

Why we flagged it

The bill's operative mechanism is a direct regulatory mandate to the DOT to cap and standardize airline ancillary fees based on cost-proportionality. This is consumer protection through price regulation, not a tax, subsidy, or procedural measure.

What the text implies

• The bill does not specify enforcement mechanisms, penalties for non-compliance, or private right of action — consumers may have no direct remedy if airlines violate the rules.
• The 'reasonable and proportional' standard is undefined in the bill itself; the Secretary has broad discretion to set the threshold, which could result in weak or strong enforcement depending on administration.
• Airlines may respond by bundling fees into base fares or reducing service tiers, shifting costs to all passengers rather than only those using ancillary services.
• The family co-location mandate (children under 13) creates a carve-out that may be difficult to enforce and could incentivize airlines to charge for seat selection in ways that circumvent the rule.

Who it affects

Consumers gain direct protection against inflated airline fees and transparency about cost-based pricing. Families with children under 13 gain a specific right to co-location without surcharge. The bill restrains airline pricing power, not consumer rights or remedies.

Who stands to gain

• airline passengers (reduced fees)
• families with children (co-location guarantee)
