Real Story: Michael's Same-Day Save
"My meeting ended 4 hours early. I was sitting at O'Hare thinking I'd have to wait until 9 PM for my flight. I called AirOnPrice and within 15 minutes, they found a seat on an earlier flight — with NO change fee. The agent knew a 'same-day confirmed' trick that the airline app didn't show. I was home for dinner."

Same-Day Change Secrets the Airlines Don't Advertise
Pro Tip: The 4-Hour Window
Most same-day changes must be made at least 4 hours before your original flight. After that, options get limited. Call 1-844-656-7300 as soon as your plans change.
Step-by-Step: How to Change Your Flight Today
- Check availability first — use the airline app to see if seats exist on earlier/later flights
- Call before going to the airport — phone agents have more flexibility than kiosk
- Mention any delays or issues — weather, maintenance, or missed connections can waive fees
- Ask about standby — it's often free and gets you on the next available flight
- Get confirmation in writing — screenshot your new itinerary immediately
