Travelers have found it’s best to book a flight 13 days in advance to save up to 36% compared to booking the same week of travel. As your travel date approaches, the cost of this flight route may potentially increase. While opting to book 13 days out may not be an option for all, there are still additional ways to secure a deal in the near future. You might find a flight from Irvine to Bulgaria 1-2 weeks in advance for as low as $672, or $914 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in June. For low rates, March can be a great choice for travel to Bulgaria. Flights to Bulgaria from Irvine in March are about $894 on average during March, but can be found for as low as $537.
Regardless of the time of day you decide to fly, the ticket price will remain around the same. Book flights from Irvine to Bulgaria as you normally would.

Flight was delayed 2 hours due to technical issues they were having at Zurich airport according to the swiss agent when I called. This caused my connection flight to be unviable. The swiss agent was helpful in finding me a partner airline to fulfill my need to get to final destination in eastern Europe. However, the only flight the agent was originally able to find me was a connecting flight through Frankfurt with a 7 hour layover and not only that but they didnt have space on the flight without upgrading me to a higher cabin class at my expense of 384 euro. I asked if this could be waived since the technical issues were not my fault from the beginning and the agent stated they arent. I ended up paying the extra 384 euro for the agent to call me back an hour later stating he found another flight through Munich with only an hour and a half layover which was great, but when I asked for the 384 euros to be refunded he stated that was included in the price difference for this flight and there was nothing he could do about that. I feel like I got scammed out of that 384 euros as that was a cabin upgrade for a flight I never ended up taking that was supposed to be my replacement for an error they were having on their end. I am grateful for the agent finding me replacement flights that worked in my favor time wise but not in being swindled out of extra charges. I also paid 85 USD to "pick my seats" (which honestly feels like a cash grab on behalf of airlines these days anyways) on my original swiss flight that I did not receive back either since I could not pick my seats on the replacement flights as well. Way to use flight delays for swindling your customers Swiss. Kayak was great as usual but I did not have any communications with Kayak directly for this ordeal it was all through Swiss airlines.
