Hmm. #301 would probably continue the scheduling SNAFUs from the tail-end of the previous season.

Zero is highly frustrated that Britannia and Britannia East each thought the other was supposed to face Greater East Asia in an exhibition match so neither turned up. Meanwhile, Buffalo and Wildcat are battling transportation woes to get to their match against Greater East Asia at Wake Island. At the last minute - possibly with pilots on the field - the match is called off until the association can get this under control. Much pouting from both sides.

Early episodes for the Atlantic Conference might be:
Battle over Barking Creek - Spitfire vs Hurricane friendly match
Rosyth - Ju-88 visits for pre-season match and Spitfire wins. Hurricane warns her not to get cocky, this clearly wasn't Germania's A-game.
(title unknown) - He-115 visits and the overconfident Spitfire gets in over her head before Hurricane demonstrates how it's done.

Following this, Hurricane packs and heads off to France, who'll be hosting the matches for the main season. First matches against Me-109 are uneven, leading to bad. Meanwhile Spitfire is fielding home games but they'll team up from episode #108 onwards with games shifting to British soil.

Also, Britannia is perhaps smaller than it used to be and accepting foreign students - Poles, Czechs, etc to fill their classes out? They might be background students only.
