Many airlines are starting to look towards replacing their 767 fleets. However, there is an issue:
How will airports prepare for the 787/A350? The main problem is that the 787-8, 787-9, and all A350s require larger gates. The 787-3 has been a slow seller, only selling so far to Japanese airlines. Some gates are not wide enough to get 787-8s/-9s or A350s. For example, at ATL, only Concourse E features gates wide enough. While Delta will probably keep some 767-300ERs for domestic routes in the short term, they will need to be replaced in the long term. Delta is considered a likely customer for the 787. While the upcoming Concourse F will add a few new international gates, it still won't be enough to handle all of Delta's combined international/domestic widebody traffic. Perhaps in the future, the airport planners at ATL will need to widen some gates at Concourse T, which is used by many of Delta's domestic widebody aircraft.
Does anyone know of other airports that may run into the same issue?
