A traveller recently asked and subsequently answered a question regarding transfer between PVG and SHA airports in Shanghai on China Eastern. The airline apparently does provide a voucher for free transfer if asked. This seemed surprising since nobody could find this information on the airline's web site.
Wikipedia provides a list of Metropolitan area airport codes of which the most well known ones are:
- NYC: JFK LGA EWR
- LON: LHR LGW LCY STN LTN SEN
- PAR: CDG ORY LBG BVA
- TYO: NRT HND
When an airline sells a ticket that requires transport between airports, this can in many cases be expensive.
I found two explicit cases where an airline publishes a policy for free ground transport:
Delta Airlines includes the following in their International Conditions of Carriage:
RULE 30 GROUND TRANSFER SERVICE
Delta or Delta Connection passengers making connections between LaGuardia Airport (LGA) or Newark International Airport (EWR) and John F. Kennedy International Airport (JFK) to or from Delta transatlantic flights will be provided ground transportation between JFK airport and LGA/EWR airports at no additional charge
GOL publishes the following on their website for Sao Paolo:
The free shuttle service GOL provides is subject to availability
To use the shuttle service between GOL airports, show the driver your boarding pass (in print or on a mobile device) or the receipt for your ticket purchase, along with your ID.
Delta Air Lines and AirFrance/KLM passengers can also use the shuttle for the CGH-GRU-CGH route by showing the driver their boarding pass or ticket purchase receipt, along with an ID.
Question: How is it possible to generally find out whether an airline provides free transport between airports co-located in the same city? e.g. are there any other examples of airline provided free transport in Terms and Conditions, Conditions of Carriage, or Fare Rules such that the wording could more easily be searched for when looking at other airlines? Or is the only option to ask the airline themselves at the airport?
