Well 2 x daily EDI-BHX wouldn't be enough. It's a busy business route and has had multiple frequency for decades now (as has GLA very similarly) I think that would not give business the flexibility it needs. The train is 4h30m fastest, at a frequency of only every two hours so you spend 9 hours minimum on the train that will require an overnight stay unlike a day or half day return by air. Both routes have been served by 1-11's, 737 and A319 with BA (some ATP off peak) in the past, although there was feed to BA hub at BHX, until they pulled out, admittedly but frequency has still been maintained. Although now retired and re-located, I have in the past been a frequent business user BHX-EDI/GLA and frequency is very important as it's possible with the schedule to use time efficiently. I think it really needs to remain at good daily spread service and 1 on Saturday is wholly inadequate. I hope you're wrong on your suggestion.
