Air travel in 2025 is changing more quickly than ever before, with many travelers experiencing new fees and restrictions after they booked their tickets. Those new airline rules and policies are changing the experience of flying in ways that even seasoned travelers have started to come to terms with. This guide outlines essential updates, unique airline policies, and flying tips that will prevent you from being surprised at the gate.
1. The End of Bags Fly Free: Southwest’s Major Shake-Up
For decades, Southwest Airlines was the go-to choice for budget-conscious travelers. But under the new airline rules, the famous “Bags Fly Free” policy is officially gone.
- First checked bag: $35
- Second checked bag: $45
- Travel credits now expire: Flight credits issued after May 28, 2025, will expire within 6 or 12 months, depending on fare type.
- Assigned seating is coming in 2026: Say goodbye to the A–B–C boarding system and hello to paid seat selection.
Traveler takeaway: When planning your trip, factor in baggage costs and new seating fees. What once made Southwest different now looks a lot more like every other carrier.
2. Delta’s Controversial “Solo Traveler Surcharge”
One of the most controversial new airline rules comes from Delta. Reports revealed that solo travelers were being charged up to $90 more per ticket than passengers booking in pairs. Although Delta has scaled back this policy after many travelers raised their concerns, it does illustrate and signify how airlines are using dynamic pricing to discreetly adjust.
Flying tips and tricks:
Before you book, compare fares for one vs. two passengers even if you’re flying alone. This simple check can expose unfair price differences and save you money.
3. United Airlines’ Strict 45-Minute Check-In Deadline
As of June 3, 2025, United Airlines has rolled out one of the most rigid airline check-in rules yet: passengers must be checked in online or in person, at least 45 minutes before domestic flights. Even if you arrive one minute late, the system reportedly blocks check-in entirely.
Smart move: Always check in online via the United app 24 hours before departure. Don’t risk being denied boarding because you missed the cutoff.

4. Power Bank Crackdown: Know the TSA Power Bank Rules
Following incidents involving battery fires mid-flight, airlines, including Southwest, are enforcing stricter TSA power bank rules.
- Portable chargers cannot be used while stowed in overhead bins.
- Always keep power banks in your personal item, not your carry-on or checked luggage.
- Avoid cheap or uncertified battery brands that may increase fire risks.
This is one of the new airline rules that’s purely about safety, but ignoring it could result in confiscated devices or boarding issues.
5. UK ETA Requirement for US Travelers
Started in January 2025, the UK introduced a new entry process called the Electronic Travel Authorization (ETA). This affects all US and Canadian visitors.
- Cost: £16 (around $18 USD)
- Validity: Two years, multiple trips
- Apply: Online or through the UK ETA app
Airlines will verify your ETA before boarding, so do apply early! This change coincides with other updates to the airline baggage policy and travel documents applying to airports and airlines around the world as part of the ongoing tightening of border and boarding of the process.
6. Delta and United’s Loyalty Partnership Shake-Up
In a rare traveler-friendly update, United and JetBlue’s new partnership allows members to earn and redeem miles across both airlines, enjoy shared lounge access, and get elite status perks. These new airline rules show not all changes are bad; this one actually rewards loyal travelers with more flexibility.
7. The Hidden Fees You Didn’t Expect
If you thought baggage fees were bad, brace yourself for the next wave of hidden airline fees:
- Seat selection “bundles” that quietly increase the total fare.
- “Solo traveler” add-ons disguised as system pricing.
- Processing surcharges when booking through third-party sites.
Always read fare details carefully before checkout and compare total costs across platforms, not just the ticket price.
8. Staying Safe with Smart Preparation
With so many shifting rules, knowing how to prepare for a flight is more critical than ever.
Checklist before you fly:
Review your airline’s official policy page weekly before travel.- Check if airline baggage policy updates affect your route.
- Verify any changes in airline check-in rules or timing.
- Pack power banks properly (in personal items).
- Apply for travel authorizations (like the UK ETA for US citizens) well in advance.
A few minutes of preparation now could save you hundreds later.
9. A Look Ahead: What’s New in Air Travel for 2026
Looking to the future, aviation experts are even more excited about the new policies the airlines are moving towards personalization and automation, from AI seat pricing to biometric boarding. Some airlines are testing fees based on carbon emissions or luggage weight precision. We have no indication if these will become a new status quo, but one thing is clear – you need to pay attention.
Conclusion
The airline industry is rapidly evolving. With tighter check-in periods, changing airline bag regulations and surprise fees like Delta’s solo traveler fee, it’s never been more prudent to stay up-to-date on new airline rules.
