My favourite Klaine fic that features a lot of Brittana is ‘You can always find me here’ by GleekMom. Some other good ones are: ‘Lottery’ by Sunshineoptimismandangels, ‘Ready to Fly’ (S3 Edition) by GleekMom, ‘Tumblin’ by mmerainbows and ‘Hold the line’ by Dontbefancy.
These are great suggestions @gorgxoxus. I’m going to add one of my fics at the end of the list that features Brittana and a Santana/Blaine friendship. - HKVoyage
You Can Always Find Me Here by GleekMom
It was a chance meeting, an instant connection, a childhood of friendship, and a lifetime of love. A Kid!Klaine AU.

Lottery Verse by @sunshineoptimismandangels
When it is the Government that chooses your Lifemate, the person you have to spend the rest or you life with, by drawing names from a national lottery there are a lot of things that can go wrong. Kurt however, has always dreamed about the day he'd met and hopefully fall in love with his Lifemate and when the government pairs Kurt with Cooper Anderson a handsome and charismatic older man Kurt can't wait to start their life together.
Of course Kurt never dreamed that maybe his Lifemate wouldn't be right for him, or that he'd have a charming younger brother named Blaine who is everything Kurt has ever wanted. What do you do when the Government pairs you with the wrong Anderson brother?
(Klaine centric romance with some Kurt/Cooper and Blaine/Sebastian)

Ready to Fly Verse by @gleekmom
Blaine’s Coming Out Story. He knew it wouldn’t be good. He didn’t know how bad it would get.
HKVoyage comment: The series doesn’t have a summary, but basically, each story follows the run up to Glee, and a season of Glee through Blaine’s experiences. This series definitely includes a strong Blaintana relationship.

Tumblin’ by @mmerainbows
Competitive cheer is serious business as far as Kurt Hummel is concerned and he’s not about to let some freshman like Blaine Anderson come in and swoop up everything he’s worked so hard for in the past few years. Klaine!AU

Everyone is a senior, marching band is the new glee club and Blaine is the new kid set to topple Kurt’s well-earned, and long-awaited reign as the lead trumpet in their award-winning ensemble.
