My impression was that Allentown was not on SW''s "A" list. First of all, you can''t fly it to BWI. Since SW is trying to tie all Eastern traffic to BWI that would be a SIGNIFICANT drawback. Its virtuallly impossible to get 10 flights out of Allentown without going to BWI. Don''t tell me that you could fly 2- BNA, 2-MCI, 4 - MDW, 2 -MCO. SW has not started a city with flights going into MDW since BDL. SW has eschewed adding MDW flights to ALB, BUF and ORF, why would they now start them again to ABE? Same for BNA they don''t fly to ALB, BUF and ORF why would they start flying to ABE. Based on current history PVD, MHT, BDL, RDU, ISP, ALB, BUF, ORF they start out with a great number of flights to BWI. I can''t see why SW would break the model for ABE.
My best guesses would be in South Carolina and when ISP opens up they would go to RIC.
