Only if you let it be. Your stress has no impact on prices so why bother.
Sing unto God, sing praises to his name: extol him that rideth upon the heavens by his name JAH, and rejoice before him. KJV Psalm 68:4
And then there's the unexpected tricks of Airline Roulette! Saw great prices direct for flights to Jamaica, pounced on them. All paid for. Great price. Great time. Direct. Hotels booked ..... and here comes the exciting part - the airline cancelled the flight with no direct replacement. God has a killer sense of humour!
We rallied and rebooked. It was a tricky one! Sometimes, you just don't know!
If you book with Southwest you can rebook if the price goes down without any fee. I changed my flight 3 times because the price came down, plus there are still 2 free bags on international flights.
