WinAirlines Casino Promo Codes - Where to Enter and How to Activate

Promo codes at WinAirlines Casino unlock specific recurring deposit bonuses. The code is entered either during the login flow or in the promo code field at the deposit step - not during the initial registration form.

Two codes are currently confirmed as active: RELDAY for the Sunday Reload and 50HIGH for the Highroller Bonus.

Where to Enter a Promo Code

The promo code field appears at two points in the account flow. The first is on the login screen, where a promo code entry option is available before you sign in. The second is inside the deposit section - look for the promo code field on the deposit form before confirming the transaction amount.

Enter the code exactly as shown, including capitalisation. Codes are case-sensitive. Once applied, the bonus tied to the code will activate on the qualifying deposit.

Active Promo Codes and Their Conditions

The two confirmed recurring codes and their conditions are listed below.

Both codes apply to deposit bonuses only. RELDAY is available on Sundays; 50HIGH can be used once every three days. Standard wagering requirements apply to all bonus funds activated through these codes.

What to Do If a Code Does Not Work

If a promo code returns an error or does not apply a bonus after deposit, check the following before contacting support.

• Confirm the code is entered exactly as shown - no spaces, correct capitalisation
• Check whether the code has a day restriction: RELDAY is Sunday only; 50HIGH has a three-day cooldown between uses
• Confirm your deposit meets the minimum amount for that code (€30 for RELDAY, €300 for 50HIGH)
• Check whether you already have an active bonus with an unmet wagering requirement - some codes will not stack with an existing active bonus
• Confirm the offer is available in your registered country

If the code still does not apply after these checks, contact the support team via live chat with the code name and your deposit amount. Support is available 24 hours a day.

Where to Find New Promo Codes

Active promo codes are listed in the promotions section of your account and in the Bonus Hub, accessible from the main menu. New codes tied to seasonal events or network promotions appear there when active.

FAQ

When do I enter a promo code - at registration or at deposit?

Promo codes are entered at the login step or in the deposit form, not during initial registration. The deposit form has a dedicated promo code field that appears before you confirm the transaction.

What is the promo code for the Sunday Reload?

The code is RELDAY. It activates a 25% match bonus up to €100 on Sundays, with a minimum deposit of €30. Enter it in the promo code field before confirming your Sunday deposit.

What is the promo code for the Highroller Bonus?

The code is 50HIGH. It activates a 50% match up to €500 with a minimum deposit of €300. The code can be used once every three days.

Can I use a promo code on my first deposit?

The welcome bonus activates automatically on your first qualifying deposit without a code. Promo codes like RELDAY and 50HIGH apply to recurring deposit bonuses after the welcome package is complete. Check the Bonus Hub for any code-specific first-deposit offers that may appear in your account.

Why is my promo code not working?

The most common reasons are: incorrect capitalisation, using the code on the wrong day (RELDAY is Sundays only), a deposit below the minimum threshold, an existing active bonus with unmet wagering, or the offer being unavailable in your country. If none of these apply, contact live chat support with the code and deposit details.
