A pure date change moves you to a new day between the same two airports. A route change moves you between different airports, and the airline treats it as a fundamentally different operation. Sometimes it works within the same ticket, sometimes it requires a full reissue, and sometimes it is simply cheaper to buy a new ticket.
Types of route change
- Same city, different airport: LGA to JFK, LHR to LGW, MAD to Getafe.
- Different city on the same continent: BOS to PHL, MAN to LHR.
- Different continent entirely: unusual and almost always requires a new ticket.
- Add or remove a stopover: converts a nonstop into a connection or vice versa.

Same-city, different-airport
The friendly case. Most airlines allow a route change within a co-terminal - a group of airports serving the same metropolitan area.
| Metro | Co-terminal airports |
|---|---|
| New York | JFK, LGA, EWR |
| London | LHR, LGW, LCY, STN, LTN |
| Tokyo | NRT, HND |
| Paris | CDG, ORY, BVA (some carriers) |
| Milan | MXP, LIN, BGY |
| Washington D.C. | IAD, DCA, BWI |
For most legacy carriers, a co-terminal change is priced as a fare difference only, no change fee. The system will price it correctly if you enter the new airport in the change tool. On low-cost carriers this rarely works and you often need to cancel and rebook.
Different city entirely
The harder case. If you want to move from a Chicago departure to a Boston departure on the same date, the airline sees it as a completely different fare and reissues at the current price. That price on close-in dates can easily exceed the original ticket.
The exception is if the original ticket was a round-trip where both directions can benefit from the change. Reissuing a JFK-LAX round-trip as an EWR-LAX round-trip is usually straightforward because the airline is not building a new fare from scratch, just applying an existing one.

Adding a stopover
Adding a free stopover en route to your destination is one of the more interesting change requests. It only works on carriers that publish stopover-friendly fare rules, but on those carriers it can turn a boring connection into a mini-trip.
Airlines that offer free stopovers as a feature:
- Icelandair: up to 7-night stopover in Reykjavik on any Trans-Atlantic route, free.
- TAP Portugal: up to 10-night stopover in Lisbon or Porto, free.
- Emirates: 1 or 2-night 'Dubai Connect' stopover with hotel included on qualifying connections.
- Turkish Airlines: 1 or 2-night hotel provided in Istanbul on qualifying long connections.
- Copa Airlines: free stopover in Panama City.
- Singapore Airlines: KrisFlyer members can add a stopover on award tickets.
Adding a stopover after booking is possible on some of these but not all. Icelandair and TAP support it through their manage-booking tool. On Emirates and Turkish, you generally have to build the stopover at booking or convince an agent to reprice - which turns it into a fare difference. Expect an increase of $100-300 on legacy carriers.
The cheapest stopovers are the ones you plan into the itinerary at booking. Post-booking they are almost always a reissue with a fare difference.

Frequently asked
Can I change my origin airport to one in a different country?+
Rarely. Most airline systems treat that as a new fare, which almost always exceeds the ticket value.
Does adding a stopover cost miles on an award ticket?+
Usually yes, but many airlines cap it. Singapore's KrisFlyer charges 5,000 miles for a stopover. Emirates Skywards allows one free stopover per award. Read the airline's own rules.
If I remove a stopover to make a longer trip nonstop, do I get a refund?+
Only if the new fare is lower. Nonstops usually cost more than connections, so removing a stop typically increases the fare.
