Trying to work out what this means. Suggestion is that it's only available to scheduled traffic Tuesday and Thursday?
That did have me wondering too, but the quoted NOTAM is incorrect, it should actually read...
AD SUMMER OPR HOURS CHANGE TO READ:
0720-1615 AND BY ARRANGEMENT WITH THE AD OPR (ARGYLL AND BUTE
COUNCIL C/O OBAN AIRPORT)
TUE AND THU 0700-0720 FOR SCHEDULED MOVEMENTS ONLY
AD 2 EGEO-1-1 PARA 2.3 REFERS
So, Oban is open daily 0720-1615 but opens 20 minutes earlier on Tuesdays and Thursdays, but only for scheduled movements.
