This will help Delta and American. Delta would go to terminals 2 and 3, and American will get terminal 5.
It will, but assuming a 1:1 ratio, that puts 16 airlines to vie for 14 gates in Terminal 4. HAL, VOL, VIR, SCX, WJA, ACA, AMX, AVA, and TAI would get booted from T2, while VRD, FFT, JBU, NKS, VOZ, AAY, and BTQ get booted from T3.
While T4 has gates that can accommodate a B747, with VIR supposedly getting in A380s in 2018, will the gates at T4 be able to handle that aircraft?
