You’ve got a Birthday discount from UIA!

We are pleased to offer you a birthday gift: take 20% off the UIA flight fares for your upcoming Birthday!

The 20% discount applies to fares if you buy UIA tickets within +/- 1 month of your Birthday (no earlier than 1 month before and no later than 1 month after).

Invite up to five travel companions – your guests can enjoy the 20% discount, too.

Celebrate your Birthday while travelling!

The 20% Birthday discount* terms and conditions:

You can buy both one-way and round-trip tickets for any UIA scheduled flight operated under the PS code (0001-0999).
Applies if your outbound flight is within +/- 1 month of your Birthday .
Applies to 6 people in one booking: one birthday person + 5 passengers travelling together (provided that the reduced tickets are for the same flight and the same travel dates).
Request your discount before booking your tickets at any UIA’s ticket office in Ukraine, Vienna or Paris, via UIA’s Contact Center (+38 044 581 5050 or 566 from cellular phone in Ukraine) or fill in a request form. The Birthday discount does not apply when buying tickets online.
Please present an ID (passport o birth certificate) when booking your flight at UIA’s ticket office or attach a scanned copy of your ID when using the online request form.
Service fee per ticket for international flights is 10 USD, and 5 USD for domestic flights across Ukraine. If you pay in UAH, an interbank exchange rate on the day of the payment applies.
* Please note.

The 20% discount applies to all published fares in all classes and does not apply to airport taxes, fees and surcharges.
The 20% discount cannot be combined with any other UIA discounts (honeymoon discount, corporate discount, age discount etc).

Wychodzi na to, że ze względu na opłatę $10 OW za każdy bilet przy locie międzynarodowym, opłacalne będzie tylko dla lotów kosztujących powyżej $50 OW. Ale zawsze może to być jakaś oszczędność.

Jest też zniżka dla nowożeńców -25%
