Spirit Airlines (NK) charges $182 for June, but adds a $35 checked bag fee—unlike Frontier’s $20 fee for the first bag.

Best Time to Book: June vs. October

Book for June 2026 travel 45 days out to secure $127 fares—prices rise 93% if booked 14 days prior. October 2026 hits $312 due to Patriots Week and Thanksgiving travel, per 2025 data from Google Flights. Delta’s peak-season pricing is 38% higher than Frontier’s base fare. I booked my March 2025 trip 52 days ahead for $112, beating the average $132 for that month. Avoid October: 67% of travelers report overpaying by $100+ compared to June.

Watch Out: Hidden Fees and Booking Traps

Booking.com adds a 14.5% "taxes and fees" charge not shown in the headline price—making a $127 flight cost $146.32. On my March 2025 trip, I paid $112 for a Frontier flight, but the final bill was $128 due to this fee. Always check the total before checkout. Delta includes one checked bag in the base fare, but Frontier’s $20 fee for the first bag (vs. Spirit’s $35) makes it the most transparent choice for budget travelers. Never book with Kayak or Skyscanner without comparing total costs.
