9.1 – SCHEDULE TIMES
a) While Scoot will make its best effort to transport you at the date(s)/ time(s) indicated on your Itinerary, we cannot guarantee schedule times. Schedules are subject to change at any time and do not form part of your contract with Scoot under these Conditions.

9.2 – SCHEDULE CHANGES: YOUR OPTIONS
If Scoot has to make a significant schedule change/ cancellation more than 24 hours before your scheduled departure time, we or our Authorised Agent will attempt to notify you per 9.1.b and provide you with one of the following options:
- Rebooking at no additional charge to another flight between the same origin and destination within seven (7) days of the changed flight in the Booking, or if Scoot will no longer serve the destination, rebooking at no additional charge to another destination for any date available for booking;
- A voucher equal to the Itinerary value – excluding any amounts for third party products and services – valid for six(6) months from the date of issue;
- Any other options set out in a Scoot schedule change or cancellations policy applicable in your jurisdiction;
- If Scoot will no longer serve the destination, a refund of the relevant Fare and Taxes and Charges.

A few passengers of my travel party are considering refunding for paid taxes and fees since we only paid a dirt cheap fare. CoC covers that too:

"4.2 – FARE RULES
Some provisions of Scoot fares differ depending on the Fare Product selected; please see the Fare Rules applicable to the Fare Product for more detailed information. Other provisions are common to all Fare Products and are listed below:
 - Scoot fares are non-refundable and cannot be downgraded;
 - A ScootBiz Class ticket may not be downgraded to an Economy Class ticket;
 - If you do not travel, Scoot may refund certain taxes and charges to you provided that:
1) We do not remain obliged to remit the tax or charge to the body (e.g. airport or government) on whose behalf we collected it;
2) You submit a request in writing within 90 days of the date of travel specified in the Booking to the address listed in 14.1;
3) A reasonable administration fee, as listed in the Fees Chart*, will be deducted from the amount. If the administration fee exceeds the amount of refund, no refund will be paid"
