The SHL S17 has been issued on 11 September 2017. Since that date ACNL signals a significant increase in cancellations.
Because of the agreed historics deadline ACNL strongly requests to return immediately all slots for the remainder of the season that will no longer be operated.
Cancellations after the SHL will be monitored and may still influence the SHL S17 (IATA WSG paragraph 9.4.2).
Airlines may receive a final SHL latest 28th of September. Any changes after the 28th until EoS will be taken into account at the SAL S18.
