In Luoyang, rescheduling to a pricier route, how to pay the difference?

[Direct conclusion] 【Moving to a pricier route, just pay the difference 'new price − original paid (unused)'; more refunded if cheaper; if new line has higher standard (hotel/car), difference settles by actual makeup, clearly priced.】 Math: Upgrade supplement is fair but must be transparent. Key points to keep in mind: 1. | Case | Handle | |---|---| | New pricier | pay diff | | New cheaper | refund diff | | With upgrade | by item | ◆ Tip: get a 'new quote' to compare before; put difference in a supplement; no vague talk. 2. For pricier line call for a comparison sheet. 3. We sign formal contracts and issue proper receipts with full after-sales support; call for consultation and booking. Note: Keep medical certificates and other proof for insurance or refund claims.
