请教一道3月JJ AA作文提纲

 油价上涨和开辟新的航线是航空公司利润下滑, 但是其他公司也收到油价上涨的影响, 但是利润并没有下滑. 所以开辟新航线是主要原因. 建议取消新的航线
                

1. assumptions that other airlines did not implement measures to counteract the increase in oil prices

2. potentially unappropriate comparison

3. hasty conclusion (should consider new airline's benefit, the expectation of the future, other possible measures to raise profit)

4. lack of quantiative support (the relative importance of oil and new paths, the cost-benefit analysis of cancelling the new paths)
